Once, Sayyiduna Umar Farooq (may Allah be pleased with him) asked: Who knows about Laylat al-Qadr, when does it occur? Upon this, Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) said: "Laylat al-Qadr is in the last ten nights of Ramadan, either after seven nights have passed (the twenty-seventh night) or when seven nights remain (the twenty-third night)."
