Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: When the Messenger of Allah (peace and blessings be upon him) returned from Ta'if, he stayed at al-Ji'ranah and distributed the spoils of war there, then he performed Umrah from there, and that was when two nights of Shawwal remained.
