Muwatta Malik, Book 36, Hadith 31 (USC-MSA) ⓘ
Yahya related to me from Malik from Amr ibn Yahya al-Mazini from his father that the Messenger of Allah, may Allah bless him and grant him peace, said, "There is no injury nor return of injury."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَمْرِو بْنِ يَحْيَى الْمَازِنِيِّ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ ضَرَرَ وَلاَ ضِرَارَ " .
