Al-Tusi, Ibn Baabwayh, and others have reported through valid chains of authority that Imam AliAmeer al-Momineen(a.s.) said, “Whoever wishes that he leaves this worldly life as pure of sins as untainted gold and none will demand him to be sued for a wrongdoing, must recite twelve times after each of the five obligatory prayers the Chapter that describes Almighty Allah; namely, Surah al-Tawheed. He may then stretch his hand and pray Almighty Allah with this supplicatory prayer, which is one of the redeeming matters that Allah’s Messenger (s.a.w.a.) taught and ordered me to convey to al-Hasan and al-Husayn (a.s.):

اَللّهُمَّ اِنّى اَسْئَلُكَ بِاسْمِكَ الْمَكْنُونِ الْمَخْزُونِ الطّاهِرِ الطُّهْرِ الْمُبارَكِ وَاَسْئَلُكَ بِاسْمِكَ الْعَظيمِ وَسُلْطانِكَ الْقَديمِ يا واهِبَ الْعَطايا يا مُطْلِقَ الاُْسارى يا فَكّاكَ الرِّقابِ مِنَ النّارِ صَلِّ عَلى مُحَمَّدٍ وَآلِ مُحَمَّدٍ وَفُكَّ رَقَبَتى مِنَ النّارِ وَاَخْرِجْنى مِنَ الدُّنْيا آمِنا وَاَدْخِلْنِى الْجَنَّةَ سالِما وَاجْعَلْ دُعآئى اَوَّلَهُ فَلاحاً وَاَوْسَطَهُ نَجاحا وَآخِرَهُ صَلاحا اِنَّكَ اَنْتَ عَلاّمُ الْغُيُوبِ

The same supplicatory prayer in other validly reported copies of the tradition is as follows:

يا فَكّاكَ الرِّقابِ مِنَ النّارِ اَسْئَلُكَ اَنْ تُصَلِّىَ عَلَى مُحَمَّدٍ وَآلِ مُحَمَّدٍ وَاَنْ تُعْتِقَ رَقَبَتى مِنَ النّارِ وَاَنْ تُخْرَجَنى مِنَ الدُّنْيا سالِما وَتُدْخِلَنِى الْجَنَّةَ آمِنا وَاَنْ تَجْعَلَ دُعآئى اَوَّلَهُ فَلاحا وَاَوْسَطَهُ نَجاحا وَآخِرَهُ صَلاحا اِنَّكَ اَنْتَ عَلاّمُ الْغُيُوبِ
