وعنه رضي الله تعالى عنه قال : قال رسول الله صلى الله عليه وآله وسلم: « لا ضرر ولا ضرار». رواه أحمد وابن ماجه. وله من حديث أبي سعيد مثله وهو في الموطأ مرسل.
Narrated [Ibn 'Abbas (RA)]: Allah's Messenger (ﷺ) said: "There should neither be harming (of others without cause), nor reciprocating harm (between two parties)." [Reported by Ahmad and Ibn Majah]. Ibn Majah reported something similar to the aforesaid Hadith from Abu Sa'id's narration. It is found in al-Muwatta' in a Mursal form (missing link after the Tabi'i).
