It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, came to us and said: "The Night of Qadr was made known to me, but two men argued and I forgot it. So seek it on the twenty-first, twenty-third, and twenty-fifth night, or on the twenty-ninth, twenty-seventh, and twenty-fifth night."
