Sayyiduna Abdullah bin Ja'far (may Allah be pleased with them both) went to Abd al-Malik bin Marwan. He entered upon him while Yahya bin al-Hakam was also present there. He asked him: In what state did you leave Khibthah (the foul place)? He meant Madinah. Abdullah (may Allah be pleased with them both) said: "The Messenger of Allah (peace and blessings be upon him) named it Taybah (the pure), and you call it Khibthah?"
