Arabic (Original)
حَدَّثَنَا ابْنُ نُمَيْرٍ عَنْ مَالِكٍ يَعْنِي ابْنَ مِغْوَلٍ عَنْ مُحَمَّدِ بْنِ سُوقَةَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ إِنْ كُنَّا لَنَعُدُّ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي الْمَجْلِسِ يَقُولُ رَبِّ اغْفِرْ لِي وَتُبْ عَلَيَّ إِنَّكَ أَنْتَ التَّوَّابُ الْغَفُورُ مِائَةَ مَرَّةٍ.
English Translation
Ibn Numayr narrated to us, from Malik, that is Ibn Mighwal, from Muhammad ibn Suqah, from Nafi', from Ibn 'Umar: We used to count, for the Messenger of Allah, peace and blessings be upon him, in a single sitting, that he would say, "My Lord, forgive me and accept my repentance; indeed You are the Ever-Relenting, the Forgiving," a hundred times.
