Sahih Ibn Khuzaymah

It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that among the last supplications between the Tashahhud and Salam of the Prophet (peace and blessings be upon him) is this: « 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 » "O Allah, forgive my earlier and later sins, my hidden and open sins, and the wrong I have committed against myself, and those faults which You know better than I do. You are the One Who brings forward and the One Who puts back. There is no deity except You."
