Arabic hadith text
وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِنِّي لأَنْسَى أَوْ أُنَسَّى لأَسُنَّ ‏"‏ ‏.‏
Translation

Yahya related to me from Malik that he had heard that theMessenger of Allah, may Allah bless him and grant him peace, said, "Iforget or I am made to forget so that I may establish the sunna."
