Muwatta Imam Malik (Riwayat Ibn al-Qasim)

And with the same chain of narration (it is narrated from Sayyiduna Ibn Umar, may Allah be pleased with them both) that the Messenger of Allah, peace and blessings be upon him, said: "Indeed, Bilal gives the call to prayer at night, so eat and drink until Ibn Umm Maktum gives the call to prayer."
