Hadith 17:232
'Isa ibn Yunus narrated to us, from Yahya ibn 'Ubayd Allah al-Taymi, who said: I heard my father say: I heard Abu Hurayrah say: The Messenger of Allah (may Allah bless him and grant him peace) said: "One of you is the mirror of his brother. So if he sees any harm, let him remove it from him."
حدثنا عيسى بن يونس عن يحيى بن عبيد الله التيمي قال سمعت أبي يقول سمعت أبا هريرة يقول قال رسول الله صلى الله عليه وسلم أحدكم مرآة أخيه فإذا رأى أذى فليمطه عنه
