Musannaf Ibn Abi Shaybah

Hazrat Muslim narrates that a man came to Hazrat Ibn Abbas (may Allah be pleased with them) to ask about suhoor. One of Hazrat Ibn Abbas’s companions said to him, “Do not eat at the time when you are in doubt.” Hazrat Ibn Abbas (may Allah be pleased with them) said, “He has said nothing; eat as long as you are in doubt, until there is no doubt left.”
