Throughout Friday night, Allah (s.w.t.) calls:
"Isn’t there any believing servant who calls upon Me until before dawn so that I will grant his worldly and spiritual request?
Isn’t there any believing servant who repents his sins before down so that I will forgive him?
Isn’t there any believing servant whose sustenance is meager and asks Me to increase it before dawn so that I will increase his sustenance?
Isn’t there any ailing and believing servant who asks Me to heal him before dawn so that I will heal him?
Isn’t there any oppressed believing servant who asks Me to take his right from the oppressor before dawn so that I will help him and restore his right?"
['Uddatul Daee, Hadees 67]
Certain Days and Times have been preferred for Prayers. 'Thursday Nights' ie the Nights Preceeding Friday, have a special place in Spiritual progress;
The souls of our deceased relatives wait for gifts (such as Sura Fatiha, Sadaqa and Quran) and cry out to us. According to a Hadith, one who prays for ten deceased individuals will be unquestionably allowed to enter Paradise.
Reflect on the inevitability of our own death and the grave.
Remember the Imam of Our Time, Imam Mahdi (peace be upon him) who is Muntazar (awaits the order to return) and Muntazir (awaited by followers)
It is highly recommended to pray to Almighty Allah for the good of one’s brethren-in-faith very frequently so as to emulate the deed of Lady Fatimah al-Zahra' (peace be upon her).
Dua to be Recited in the Last Hours of Thursday
Shaykh al-Tusi has recorded that it is recommended to say the following prayer of forgiveness at the last hour of Thursdays:
allahumma salli `ala muhammadin wa ali muhammadin
O Allah, send blessings to Muhammad and his Household.
It has been authentically narrated that Imam Ja`far al-Sadiq (peace be upon him) said, “On Thursday afternoons, angels from the heavens descend to the lowest space carrying golden pens and silver papers on which they record nothing except the invocations of blessings upon Muhammad and his Household.”
Shaykh al-Tusi says it is recommended, on Thursdays, to repeat the invocations of blessings upon Muhammad and
his Household 1000 times in the following form:
allahumma salli `ala muhammadin wa ali muhammadin
O Allah, send blessings to Muhammad and the Household of Muhammad,
wa `ajjil farajahum
hasten their Relief,
wa ahlik `aduwwahum
and destroy their enemies
مِنَ ٱلْجِنِّ وَٱلْإِنْسِ
mina aljinni wal-insi
from both jinn and human beings,
مِنَ ٱلْأَوَّلِينَ وَٱلْآخِرِينَ
mina al-awwalina wal-akhirina
both the foremost and the later ones.
Great reward will be the share of him who utters this invocation from Thursday afternoons up to the last hour of Fridays.
It is recommended to recite Surah al-Jumu`ah (No. 62) in the first unit of the Maghrib (Sunset) and `Isha' (Evening) obligatory Prayers, and to recite Surah al-Tawhid (No. 112) in the second unit of the Maghrib Prayer and Surah al-A`la (No. 87) in the second unit of the `Isha' Prayer.
Duas to be Recited on the Night Preceeding Friday
According to a tradition, one may repeat the invocation of blessings upon Muhammad and his Household 100 times at least at Friday nights. The more the better.
Imam al-Sadiq (peace be upon him) is reported as saying, “To invoke Almighty Allah’s blessings upon Muhammad and his Household at Friday nights is equal to winning 1000 rewards, having 1000 evildoings erased, and having 1000 ranks raised.”
Imam Ja`far al-Sadiq (peace be upon him) is reported as saying that one who says the following prayer in the last prostration of the `Isha' nafila/supererogatory prayer at Friday nights and repeats it seven times will have all his sins forgiven as soon as he accomplishes that prayer. Yet, it is desirable to repeat this deed each night:
allahumma inni as'aluka biwajhika alkarimi
O Allah, I beseech You in the name of Your Noble Face
and in the name of Your Sublime Name
أَنْ تُصَلِّيَ عَلَىٰ مُحَمَّد وَآلِهِ
an tusalliya `ala muhammadin wa ali muhammadin
to send blessings to Muhammad and his Household
وَأَنْ تَغْفِرَ لِي ذَنْبِيَ ٱلْعَظيمَ
wa an taghfira li dhanbiya al`azima
and to forgive me my grave sin.
The Holy Prophet (peace and blessings upon him and his family) is reported to have said that one who repeats the following prayer seven times at Friday night will be allowed Paradise if he departs life at that night; and one who repeats it seven times on Friday will be also allowed Paradise if he departs life on that day:
اَللَّهُمَّ أَنْتَ رَبِّي
allahumma anta rabbi
O Allah, You are my Lord;
لاَ إِلٰهَ إِلاَّ أَنْتَ
la ilaha illa anta
there is no god save You;
خَلَقْتَني وَأَنَا عَبْدُكَ وَٱبْنُ أَمَتِكَ
khalaqtani wa ana `abduka wabnu amatika
You have created me, and I am Your slave and the son of Your bondmaid;
وَفي قَبْضَتِكَ وَنَاصِيَتي بِيَدِكَ
wa fi qabdatika wa nasiyati biyadika
and I am in Your grip; and my forehead is in Your Hand;
Write (prescribe) for me freedom from pain, trouble and anxiety,make ready for me blessings and happiness, so that I do not like what You delay to come in advance,or what You make happen quickly to be delayed.
Give me contentment and an independent disposition.Make me derive advantage from the power of hearing (I listen to and accept advise and obey)
and seeing (discernment,intelligence, and perception of truth);and both of them to my inheritors
Surah's (Chapters) to be Recited on the Night Preceeding Friday
At Friday nights, it is recommended to recite the following chapters (Surah) of the Holy Qur'an:
(1) Surah al-Isra’ (Bani-Isra'il; No. 17),(2) Surah al-Kahf (No. 18),(3) the three Surahs beginning with Ta-Sin, i.e. Surah al-Shu`ara' (No. 26), Surah al-Naml (No. 27),
and Surah al-Qasas (No. 28),(4) Surah al-Sajdah (No. 32),(5) Surah Yasin (No. 36),(6) Surah Sad (No. 38),(7) Surah al-Ahqaf (No. 46),(8) Surah al-Waqi`ah (No. 56),
(9) Surah Fussilat (No. 41),(10) Surah al-Dukhan (No. 44),(11) Surah al-Tur (No. 52),(12) Surah al-Qamar (No. 54), and(13) Surah al-Jumu`ah (No. 62).
If there is not enough time to recite all these Surahs, one may choose Surah al-Waqi`ah and those preceding it [in the aforesaid list].
Imam al-Sadiq (peace be upon him) is reported to have said that one who recites Surah al-Isra' each Friday night will join Imam al-Mahdi (peace be upon him) as one of his companions.
He (peace be upon him) is also reported as saying that one who recites Surah al-Kahf at Friday nights will die as martyr and will be resurrected with and in the line of the martyrs (on the Resurrection Day).
He (peace be upon him) is also reported as saying that one who recites the three Surahs beginning with Ta-Sin at Friday nights will be included with the intimate saints of Almighty Allah, will be made in the vicinity and under the protection of Him, will never be inflicted with misery in his worldly life, and will be given beyond his pleasure on the Resurrection Day.
He (peace be upon him) is also reported as saying that one who recites Surah al-Sajdah at Friday nights will be given his Record of Deeds in his right hand, will not be interrogated about his evildoings, and will be included with the companions of Muhammad and his Household—peace be upon them all.
Imam Muhammad al-Baqir (peace be upon him) is reported to have said that one who recites Surah Sad at Friday nights will be granted the welfare of this world as well as the Next World in such an excellent way that none would deserve except Prophets and archangels and will be allowed to Paradise as well as all those whom he loves among his household including the servants.
Imam Ja`far al-Sadiq (peace be upon him) is reported to have said that one who recites on Fridays or at Friday nights Surah al-Ahqaf will be saved, by Almighty Allah, from terrors in the worldly life and will be secured from the horror of the Resurrection Day.
He (peace be upon him) is also reported as saying that one who recites Surah al-Waqiah at Friday nights will be loved by Almighty Allah, all people will be made to love him, will be saved from all miseries, poverty, neediness, and misfortunes in this worldly life, and will be joined to the companions of Imam `Ali Amir al-Mu'minin (as) because this Surah is ascribed to him.
It has been also narrated that to recite Surah al-Jumu`ah at Friday nights is decided as expiation (forgiving the sins) for the evildoings committed throughout the week. A similar merit has been narrated for reciting Surah al-Kahf at Friday nights or after the two obligatory Dhuhr and `Asr Prayers on Fridays.
Salaats for the Night Preceeding Friday
It is worth mentioning that it is highly recommended to offer many (supererogatory) prayers at Friday nights such as;
A two-unit prayer in each of which one should recite Surah al-Fatihah once and repeat Surah al-Zalzalah (No. 99) fifteen times. It has been narrated that one who offers this prayer will be saved, by Almighty Allah, from the grave torment and the horrors on the Resurrection Day.
A two-unit prayer in each of which after Sura Hamd, recite Sura Tawheed 70 times. Upon completion of the prayer say 'Astaghfirullah' 70 times.
It has been reported from the Holy Prophet, 'If one recites (this prayer) then by the One Who has sent me with truth anyone who performs this act and does Isteghfar then even if he supplicates for my whole nation the Almighty would accept his supplication and would enter the whole nation in Paradise.
Allah grants him for each letter in the astagfirullah domes like stars in the sky, in each dome of the palaces by the number of stars in the sky, in each palace by the number of stars in the sky - chests, in each chest by the number of stars in the sky, beds, on each the bed was covered with blankets by the number of stars in the sky, etc ..., and Allah will bestow all these rewards on those who perform these two raka'ats.' [Reference: Biharul Anwaar, Mustadrak al-Wasail]
A six-unit prayer in each of which after Surah Hamd recite Ayatul Kursi and Surah Kafiroon once each and Surah Tawheed thrice.
After the prayers, recite Ayatul Kursi three times. For one who recites this prayer the Almighty Allah appoints an angel to purify his sins who purifies his sins and in their place writes good fortune and bestows him whatever he desires.
Prayer of Imam Mahdi (peace be upon him) on Night of Friday
Quoting the book of Kunuz al-Najah by Shaykh al-Yabrisi, the author of al-Najm al-Thaqib mentioned the following statement to have come from Imam al-Mahdi (peace be upon him) : “Whoever has a request to be urgently granted by Almighty Allah, may bathe himself after midnight at a Friday night, directs towards his place of prayer, and offers a two unit prayer. In the first unit, he may recite Surah al-Faatehah, but when he reaches this holy verse, he should repeat it one hundred times:
إيّاك نعبد وإيّاك نستعين
He may then continue reciting this Surah. After that, he may recite Surah al-Tawheed one time only. In the genuflection of each unit, he may repeat the following seven times:
سبحان ربّى العظيم و بحمده
In the two prostrations of each unit, he may repeat the following seven times:
سبحان ربّى الاعلى و بحمده
Upon accomplishment of the prayer, he may beseech Almighty Allah using this supplicatory prayer. If he does, Almighty Allah will most certainly grant him his request unless it results in rupture of relations with one’s relatives:
You may now mention the one whom you anticipate to harm you by name and the father’s name (i. e. so-and-so the son of so-and-so) and beseech Almighty Allah to repel his harm and save from his evils. Most certainly, Almighty Allah will do, if He wills.
Then, you may prostrate yourself, submit your request, and beseech Almighty Allah earnestly and purely. Verily, if any believing man or woman offers this prayer and says this supplicatory prayer, the doors to the heavens will be opened before him/her so that his/her requests will be granted and his/her prayer will be immediately responded, no matter what his/her prayer may be. This is one of the favors Almighty Allah has bestowed upon people and upon us."
Following Imam Ja`far al-Sadiq (peace be upon him) it is recommended to have pomegranate at Friday nights, preferably before going to sleep. In this respect, it has been narrated that to eat pomegranate before going to sleep procures security until morning. It is also instructive to extend a handkerchief on the ground so as to save all the seeds of a pomegranate from loss and then eat them all. It is also recommended not to share the pomegranate with anyone.
Recite last 10 Verses of Sura Kahaf (18) on Thursday Nights before sleeping for salvation from the Dajjal
