Mukhtasar Bukhari

Narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Bilal (may Allah be pleased with him) gives the call to prayer at night, so eat and drink until Ibn Umm Maktum (may Allah be pleased with him) gives the call to prayer." Sayyiduna Ibn Umar (may Allah be pleased with them both) says that Sayyiduna Ibn Umm Maktum (may Allah be pleased with him) was a blind man; he would not give the call to prayer until people said, 'Morning has come, morning has come.'"
