Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn �Isa from Ali ibn al-NuMan from certain individuals of his people from abu �Abd Allah, recipient of divine supreme covenant, who has said the following:

Amir al-Mu�minin, Ali ibn abu Talib (as), has said, �Whoever just before beginning the prayer says the following will be with Muhammad and the family of Muhammad. �O Lord, I am turning to You through Muhammad and his family. I assign them as the lead for me before my prayer and seek nearness through them to You, grant me respect through them in this world and in the next life and of those close (to You). You have obliged me for making me know them, conclude for me with obedience to them, knowing them well, and under their guardianship; it is the salvation and end it for me in this (belief), You have power over all things.� Then complete the prayer and say, �O Lord, place me with Muhammad and the family of Muhammad, in good health and in suffering, place me with Muhammad and the family of Muhammad in every dwelling and place of return. O Lord, help me to live in the way of life of Muhammad and the family of Muhammad and die like the death of Muhammad and the family of Muhammad, place me with them in all habitations and do not separate me from them. You have power over all things.��

Dua to be recited after every obligatory prayer:

 

في كتاب جمال الصالحين عن مولانا الصادق (عليه السلام) أنه قال: إن من حقوقنا على شيعتنا أن يضعوا بعد كل فريضة أيديهم على أذقانهم ويقولوا ثلاث مرات: " يا رب محمد عجل فرج آل محمد يا رب محمد احفظ غيبة محمد، يا رب محمد، انتقم لابنة محمد عليها السلام

 

"O' Lord of Mohammad (saww), Hasten the deliverance of Aal-e-Mohammad (as)"
"O' Lord of Mohammad (saww), Protect the occultation (Ghaibah) of Mohammad"
"O' Lord of Mohammad (saww), Take revenge for the daughter of Mohammad (sa)"

Right of the Imam's (as) upon their friends and Shia's to recite the following dua:

 

وَجَدْتُ فِي كِتَابٍ مَجْمُوعٍ بِخَطٍّ قَدِيمٍ ذَكَرَ نَاسِخُهُ وَ هُوَ مُصَنِّفُهُ أَنَّ اسْمَهُ مُحَمَّدُ بْنُ مُحَمَّدِ بْنِ عَبْدِ اللَّهِ بْنِ فَاطِرٍ مَنْ رَوَاهُ عَنْ شُيُوخِهِ فَقَالَ مَا هَذَا لَفْظُهُ حَدَّثَنَا مُحَمَّدُ بْنُ عَلِيِّ بْنِ رِقَاقٍ الْقُمِّيُّ قَالَ حَدَّثَنَا أَبُو الْحَسَنِ مُحَمَّدُ بْنُ أَحْمَدَ بْنِ عَلِيِّ بْنِ الْحَسَنِ بْنِ شَاذَانَ الْقُمِّيُّ عَنْ أَبِي جَعْفَرٍ مُحَمَّدِ بْنِ عَلِيِّ بْنِ الْحُسَيْنِ بْنِ بَابَوَيْهِ الْقُمِّيِّ عَنْ أَبِيهِ قَالَ حَدَّثَنَا جَعْفَرُ بْنُ عَبْدِ اللَّهِ الْحِمْيَرِيُّ عَنْ مُحَمَّدِ بْنِ عِيسَى بْنِ عُبَيْدٍ قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ أَبِي هَاشِمٍ عَنْ أَبِي يَحْيَى الْمَدَنِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ع أَنَّهُ قَالَ‏ مِنْ حَقِّنَا عَلَى أَوْلِيَائِنَا وَ أَشْيَاعِناَ أَنْ لَا يَنْصَرِفَ الرَّجُلُ مِنْهُمْ مِنْ صَلَاتِهِ حَتَّى يَدْعُوَ بِهَذَا الدُّعَاءِ وَ هُوَ

Narrated from Abi Abdillah Imam Sadiq (as) that it is from the Our rights upon our friends and our Shia's that they should not turn away after their prayers (salah) until they recite this dua:
 

اللَّهُمَّ إِنِّي أَسْأَلُكَ بِحَقِّكَ الْعَظِيمِ الْعَظِيمِ أَنْ تُصَلِّيَ عَلَى مُحَمَّدٍ وَ آلِ مُحَمَّدٍ الطَّاهِرِينَ وَ أَنْ تُصَلِّيَ عَلَيْهِمْ صَلَاةً تَامَّةً دَائِمَةً وَ أَنْ تُدْخِلَ عَلَى مُحَمَّدٍ وَ آلِ مُحَمَّدٍ وَ مُحِبِّيهِمْ وَ أَوْلِيَائِهِمْ حَيْثُ كَانُوا وَ أَيْنَ كَانُوا فِي سَهْلٍ أَوْ جَبَلٍ أَوْ بَرٍّ أَوْ بَحْرٍ مِنْ بَرَكَةِ دُعَائِي مَا تَقَرُّ بِهِ عُيُونُهُمْ احْفَظْ يَا مَوْلَايَ الْغَائِبِينَ مِنْهُمْ وَ ارْدُدْهُمْ إِلَى أَهَالِيهِمْ سَالِمِينَ وَ نَفِّسْ عَنِ الْمَهْمُومِينَ وَ فَرِّجْ عَنِ الْمَكْرُوبِينَ وَ اكْسُ الْعَارِينَ وَ أَشْبِعِ الْجَائِعِينَ وَ أَرْوِ الظَّامِئِينَ وَ اقْضِ دَيْنَ الْغَارِمِينَ وَ زَوِّجِ الْعَازِبِينَ وَ اشْفِ مَرْضَى الْمُسْلِمِينَ وَ أَدْخِلْ عَلَى الْأَمْوَاتِ مَا تَقَرُّ بِهِ عُيُونُهُمْ وَ انْصُرِ الْمَظْلُومِينَ مِنْ أَوْلِيَاءِ آلِ مُحَمَّدٍ عَلَيْهِمُ السَّلَامُ وَ أَطْفِئْ نَائِرَةَ الْمُخَالِفِينَ اللَّهُمَّ وَ ضَاعِفْ لَعْنَتَكَ وَ بَأْسَكَ وَ نَكَالَكَ وَ عَذَابَكَ عَلَى اللَّذَيْنِ كَفَرَا نِعْمَتَكَ وَ خَوَّنَا رَسُولَكَ وَ اتَّهَمَا نَبِيَّكَ وَ بَايَنَاهُ وَ حَلَّا عَقْدَهُ فِي وَصِيِّهِ وَ نَبَذَا عَهْدَهُ فِي خَلِيفَتِهِ مِنْ بَعْدِهِ وَ ادَّعَيَا مَقَامَهُ وَ غَيَّرَا أَحْكَامَهُ وَ بَدَّلَا سُنَّتَهُ وَ قَلَّبَا دِينَهُ وَ صَغَّرَا قَدْرَ حُجَجِكَ وَ بَدَا بِظُلْمِهِمْ وَ طَرَّقَا طَرِيقَ الْغَدْرِ عَلَيْهِمْ وَ الْخِلَافِ عَنْ أَمْرِهِمْ- وَ الْقَتْلِ لَهُمْ وَ إِرْهَاجِ الْحُرُوبِ عَلَيْهِمْ وَ مَنْعِ خَلِيفَتِكَ مِنْ سَدِّ الثَّلْمِ وَ تَقْوِيمِ الْعِوَجِ وَ تَثْقِيفِ الْأَوَدِ وَ إِمْضَاءِ الْأَحْكَامِ وَ إِظْهَارِ دِينِ الْإِسْلَامِ وَ إِقَامَةِ حُدُودِ الْقُرْآنِ اللَّهُمَّ الْعَنْهُمَا وَ ابْنَتَيْهِمَا وَ كُلَّ مَنْ مَالَ مَيْلَهُمْ وَ حَذَا حَذْوَهُمْ وَ سَلَكَ طَرِيقَتَهُمْ وَ تَصَدَّرَ بِبِدْعَتِهِمْ لَعْناً لَا يَخْطُرُ عَلَى بَالٍ وَ يَسْتَعِيذُ مِنْهُ أَهْلُ النَّارِ الْعَنِ اللَّهُمَّ مَنْ دَانَ بِقَوْلِهِمْ وَ اتَّبَعَ أَمْرَهُمْ وَ دَعَا إِلَى وَلَايَتِهِمْ وَ شَكَّ فِي كُفْرِهِمْ مِنَ الْأَوَّلِينَ وَ الْآخِرِينَ ثُمَّ ادْعُ بِمَا شِئْت‏

 

 "O'Allah, I ask you by your great right, that You send blessings upon Mohammad and His Progeny (as) the pure. And You send blessings upon them that are complete and permanent and that you enter upon Mohammad and His Progeny (as) and their Lovers and their friends wherever they are, in the plains or mountains or land or sea from the blessings of my prayer that which pleases (provides coolness to) their eyes."

"Protect, O my Master, those among them who are away and return them to their families safely and provide relieve to those in grief/distress, provide comfort to those in sorrow, and provide cover to those without any cover, and satiate those who are hungry, and quench (provide water) those who are thirsty, and fulfill the debt of those in debt, and marry off those who are unmarried, and cure the sick Muslims and enter upon the dead that which pleases (provides coolness to) their eyes. And help the oppressed from the friends of the AhlulBait (as) and put out hatred (flame of war) of those who oppose."

 

"O Allah, increase Your remove your blessings from ,& let  Your terror, Your punishment, Your affliction/suffering be upon those 2 () who rejected (kufr) Your blessing, and were disloyal to your Messenger,  and accused your Prophet, and left Him (or contradicted Him), broke His covenant/agreement about His guardian and rejected his covenant/agreement in regards to His Successor after Him.  And made claim to His position and changed His rulings, and altered his tradition (sunnah), and turned upside down his religion, and lowered (belittle) the position/rank of Your Hujjah (proofs) and started/initiated oppression upon them, and setup the path of deception/betrayal upon them, and opposition to their orders, and their killing, raising of wars upon them and prevented Your Khalifah from stopping the rift, and prevented from straightening the crooked, and prevented from execution of the laws, and prevented from manifestation of the the religion of Islam, and prevented from establishing the Hudood of Quran,"

 

"O Allah, remove your blessing from those 2 () and their 2 daughters () and all those inclined towards their way, and those who follow their example and those who follow their path, and those who lead the innovations (Biddah) they established; A cursing which minds cannot comprehend and from which the dwellers of hell seek refuge."

 

"remove your blessing O'Allah, from those who believe in their () saying, and those who obey their orders, and those who call others towards their friendship and those who doubt in these 2 being Kafir from amongst the first and the last ones."

 

Then ask Dua what you wish.
