Compiled by Imam Yahya ibn Sharaf al-Nawawi
عَنْ أَبِي سَعِيدٍ سَعْدِ بْنِ مَالِكِ بْنِ سِنَانٍ الْخُدْرِيّ رَضِيَ اللهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه و سلم قَالَ: " لَا ضَرَرَ وَلَا ضِرَارَ" . حَدِيثٌ حَسَنٌ، رَوَاهُ ابْنُ مَاجَهْ [راجع رقم:2341]، وَالدَّارَقُطْنِيّ [رقم:4/228]، وَغَيْرُهُمَا مُسْنَدًا. وَرَوَاهُ مَالِكٌ [2/746] فِي "الْمُوَطَّإِ" عَنْ عَمْرِو بْنِ يَحْيَى عَنْ أَبِيهِ عَنْ النَّبِيِّ صلى الله عليه و سلم مُرْسَلًا، فَأَسْقَطَ أَبَا سَعِيدٍ، وَلَهُ طُرُقٌ يُقَوِّي بَعْضُهَا بَعْضًا.
There should be neither harming (darar) nor reciprocating harm (dirar). A hasan hadeeth related by Ibn Majah, ad-Daraqutnee and others as a musnad hadeeth. It was also related by Malik in al-Muwatta in mursal form from Amr bin Yahya, from his father from the Prophet (peace and blessings of Allah be upon him), but leaving Abu Sa’eed from the chain. And it has other chains of narrations that strengthen one another.
