حَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، وَعُثْمَانُ بْنُ أَبِي شَيْبَةَ، قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ الْفُضَيْلِ، عَنْ مُغِيرَةَ، عَنْ أُمِّ مُوسَى، عَنْ عَلِيٍّ، عَلَيْهِ السَّلاَمُ قَالَ كَانَ آخِرُ كَلاَمِ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏"‏ الصَّلاَةَ الصَّلاَةَ اتَّقُوا اللَّهَ فِيمَا مَلَكَتْ أَيْمَانُكُمْ ‏"‏ ‏.‏
Translation
Narrated Abdullah ibn Umar

A man came to the Prophet (ﷺ) and asked: Messenger of Allah! how often shall I forgive a servant? He gave no reply, so the man repeated what he had said, but he still kept silence. When he asked a third time, he replied: Forgive him seventy times daily.
