Yahya related to me from Malik that Zayd ibn Aslam said, "The Messenger of Allah (ﷺ) stopped for a rest one night on the way to Makka and appointed Bilal to wake them up for the prayer. Bilal slept and everyone else slept and none of them woke up until the sun had risen. When they did wake up they were all alarmed. The Messenger of Allah (ﷺ) ordered them to ride out of the valley, saying that there was a shaytan in it. So they rode out of the valley and the Messenger of Allah (ﷺ) ordered them to dismount and do wudu and he told Bilal either to call the prayer or to give the iqama. The Messenger of Allah (ﷺ) then led them in the prayer. Noticing their uneasiness, he went to them and said, 'O people! Allah seized our spirits (arwah) and if He had wished He would have returned them to us at a time other than this. So if you sleep through the time for a prayer or forget it and then are anxious about it, pray it as if you were praying it in its time.' The Messenger of Allah (ﷺ) turned to Abu Bakr and said, 'Shaytan came to Bilal when he was standing in prayer and made him lie down and lulled him to sleep like a small boy.' The Messenger of Allah (ﷺ) then called Bilal and told him the same as he had told Abu Bakr. Abu Bakr declared, 'I bear witness that you are the Messenger of Allah.' "
