Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) married a woman of Banu Ghifar. When she was brought in to him, she had vitiligo (baras) on her side, so he (peace and blessings be upon him) sent her back and said: "You have deceived me."
