Narrated from Sayyiduna Shaddad bin Aws (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: The chief of supplications for forgiveness (Sayyid al-Istighfar) is this: «اللَّهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ خَلَقْتَنِي وَأَنَا عَبْدُكَ وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ أَبُوءُ لَكَ بِنِعْمَتِكَ عَلَيَّ وَأَبُوءُ بِذَنْبِي فَاغْفِرْ لِي فَإِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ» O Allah, You are my Lord, there is no deity except You. You created me and I am Your servant. And I am upon Your covenant and promise as much as I am able. I acknowledge Your blessings upon me, and I confess my sins, so forgive me, for none forgives sins except You. I seek refuge in You from the evil of what I have done. Whoever says these words sincerely in the evening and dies that night will enter Paradise. Or he said:“He will be among the people of Paradise. And whoever says it in the morning and dies that day, then the same reward applies.”
