And Muhammad ibn al-Muthanna narrated to us, Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from 'Uqbah — and he is ibn Huraith — who said: I heard Ibn 'Umar, may Allah be pleased with them both, saying: The Messenger of Allah, peace and blessings be upon him, said: "Seek it in the last ten — meaning the Night of Qadr — and if any of you is weakened or unable, then let him not be overcome regarding the remaining seven."
