BAYHAQI 3018:
from ʿAlī —
[Machine] "About the Prophet ﷺ in his prayer, he said, 'When he finishes his prayer and gives the Salaam (greeting), he said: 'O Allah, forgive me for what I have brought forward and what I have delayed, and what I have concealed and what I have made public, and what I have exceeded, and what You know better than me. You are the one who precedes, and You are the one who delays. There is no god but You.' It was narrated by Yusuf ibn Ya'qoub from his father Al-Majishoon with his Isnad (chain of transmission), and this supplication was mentioned between the Tashahhud (sitting in prayer) and the Tasleem (ending of prayer), and both are mentioned in the book of Muslim."

عن علي —
عَنِ النَّبِيِّ ﷺ فِي صَلَاتِهِ قَالَ وَإِذَا فَرَغَ مِنْ صَلَاتِهِ فَسَلَّمَ قَالَ اللهُمَّ اغْفِرْ لِي مَا قَدِمْتُ وَمَا أَخَّرْتُ وَمَا أَسْرَرْتُ وَمَا أَعْلَنْتُ وَمَا أَسْرَفْتُ وَمَا أَنْتَ أَعْلَمُ بِهِ مِنِّي أَنْتَ الْمُقَدِّمُ وَأَنْتَ الْمُؤَخِّرُ لَا إِلَهَ إِلَّا أَنْتَ وَرَوَاهُ يُوسُفُ بْنُ يَعْقُوبَ عَنْ أَبِيهِ الْمَاجِشُونِ بِإِسْنَادِهِ وَذَكَرَ هَذَا الدُّعَاءَ بَيْنَ التَّشَهُّدِ وَالتَّسْلِيمِ وَكِلَاهُمَا مُخَرَّجٌ فِي كِتَابِ مُسْلِمٍ
