'Ali b. Abi Talib said: When the Prophet (ﷺ) uttered salutation at the end of the prayer, he used to say: "O Allah, forgive me my former and latter sins, what I have kept secret and what I have done openly, and what I have done extravagance; and what You know better than I do. You are the Advancer, the Delayer, there is no god but You."

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، قَالَ حَدَّثَنَا أَبِي، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي سَلَمَةَ، عَنْ عَمِّهِ الْمَاجِشُونَ بْنِ أَبِي سَلَمَةَ، عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ، عَنْ عُبَيْدِ اللَّهِ بْنِ أَبِي رَافِعٍ، عَنْ عَلِيِّ بْنِ أَبِي طَالِبٍ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا سَلَّمَ مِنَ الصَّلاَةِ قَالَ ‏ "‏ اللَّهُمَّ اغْفِرْ لِي مَا قَدَّمْتُ وَمَا أَخَّرْتُ وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ وَمَا أَسْرَفْتُ وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ لاَ إِلَهَ إِلاَّ أَنْتَ ‏"‏ ‏.‏
