It is narrated from Salim (may Allah have mercy on him) that the Messenger of Allah (ﷺ) said: "Bilal (may Allah be pleased with him) gives the call to prayer while a part of the night remains, so eat and drink until Ibn Umm Maktum (may Allah be pleased with him) gives the call to prayer. And he was a blind man; he would not give the call to prayer until it was said to him: 'You have entered the morning, you have entered the morning.'"
