Abu ‘Ali Suwayd ibn Muqarrin (may Allah be pleased with him) reported: I was one of seven sons of Muqarrin, and we had only one female servant. The youngest of us slapped her in the face, so the Messenger of Allah (may Allah’s peace and blessings be upon him) commanded us to set her free. Another narration reads: "I was one of seven siblings." Authentic hadith - Narrated by Muslim
