Hadith #505670

Yahya related to me from Malik that he had heard that A'isha, the wife of the Prophet, (ﷺ), used to say, "Breaking the bone of a muslim when he is dead is like breaking it when he is alive." She meant if done in wrong action.

وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عَائِشَةَ، زَوْجَ النَّبِيِّ صلى الله عليه وسلم كَانَتْ تَقُولُ كَسْرُ عَظْمِ الْمُسْلِمِ مَيْتًا كَكَسْرِهِ وَهُوَ حَىٌّ ‏.‏ تَعْنِي فِي الإِثْمِ ‏.‏
