عَنْ أَبِي سَعِيدٍ سَعْدِ بْنِ مَالِكِ بْنِ سِنَانٍ الْخُدْرِيِّ رَضِيَ اللهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: لَا ضَرَرَ وَلَا ضِرَارَ. حَدِيثٌ حَسَنٌ، رَوَاهُ ابْنُ مَاجَهْ وَالدَّارَقُطْنِيُّ وَغَيْرُهُمَا مُسْنَدًا، وَرَوَاهُ مَالِكٌ فِي الْمُوَطَّأِ عَنْ عَمْرِو بْنِ يَحْيَى، عَنْ أَبِيهِ، عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُرْسَلًا، فَأَسْقَطَ أَبَا سَعِيدٍ، وَلَهُ طُرُقٌ يُقَوِّي بَعْضُهَا بَعْضًا

32 – It is reported on the authority of Abī Sa’īd Sa’d bin Mālik bin Sinān al-Khudrī (may Allāh be pleased with him), that the Messenger of Allāh (peace and blessings of Allāh be upon him) said:

“There should be neither harming (ḍarara) nor reciprocating harm (ḍirār).” [A ḥasan ḥadīth reported by ibn Mājah, Dāraquṭnī and others as a musnad ḥadīth. It was also reported by Mālik in Muwaṭṭā in mursal form, from ‘Amr bin Yaḥyā, from his father from the Prophet (peace and blessings of Allāh be upon him), but leaving Abā Sa’īd from the chain. And it has other chain of authorities that strengthen one another]
