Musnad Ahmad 4278

It was narrated that ‘Abdullah said: We travelled by night with the Prophet (ﷺ) and we said: O Messenger of Allah, how about if we halt here and sleep, and our mounts can graze. He agreed and said: Let some of you guard us. 'Abdullah said: I will guard you. But then sleep overtook me; I fell asleep and did not wake up until the sun had risen, and the Messenger of Allah (ﷺ) did not wake up until (he heard) us talking. He instructed Bilal to give the adhan, then the iqamah for prayer, and the Messenger of Allah (ﷺ) led us in prayer.
