حَدَّثَنَا جَنْدَلُ بْنُ وَالِقٍ، قَالَ: حَدَّثَنَا يَحْيَى بْنُ يَعْلَى، عَنْ يُونُسَ بْنِ خَبَّابٍ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عُمَرَ
قَالَ: سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَسْتَغْفِرُ اللَّهَ فِي الْمَجْلِسِ مِئَةَ مَرَّةٍ: رَبِّ اغْفِرْ لِي، وَتُبْ عَلَيَّ، وَارْحَمْنِي، إِنَّكَ أَنْتَ التَّوَّابُ الرَّحِيمُ
“I heard the Prophet (sallallahu alayhi wa sallam), may Allah bless him and grant him peace, asking Allah to forgive him a hundred times in this assembly with the words, ‘O Allah, forgive me and turn to me and show mercy to me. You are the Ever-Turning back (to his slaves), Merciful.’”
