Arabic hadith text
وَعَن ابْن عمر قَالَ: إِنْ كُنَّا لَنَعُدُّ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الْمَجْلِسِ يَقُولُ: «رَبِّ اغْفِرْ لِي وَتُبْ عَلَيَّ إِنَّكَ أَنْتَ التَّوَّابُ الْغَفُورُ» مِائَةَ مَرَّةٍ. رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُدَ وَابْنُ مَاجَهْ
Translation
Ibn ‘Umar reported: We used to count the Messenger of God (peace be upon him) saying in a gathering one hundred times: ‘My Lord, forgive me and accept my repentance; You are the Accepter of repentance, the Forgiving.’ Ahmad, al-Tirmidhi, Abu Dawud, and Ibn Majah transmitted it. The Arabic source marks it as not studied by al-Albani.
