Hadith 6955
Sayyiduna Miswar bin Makhramah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) saying on the pulpit: "The Banu Hashim bin Mughira have sought my permission to marry their daughter to Ali, while my daughter (is already his wife). I will not give them permission, I will never give them permission. However, if he wishes, he may divorce my daughter and marry their daughter. My daughter is a part of my flesh; whatever pleases her pleases me, whatever displeases her displeases me, and whatever causes her pain causes me pain."
