Musnad Ahmad 27:454

'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from al-Zuhri, from Salim, from Ibn 'Umar, who said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: "It is not the right of a Muslim man, upon whom three nights pass, except that his will is with him."
