Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said:“Bilal’s call to prayer should never prevent any one of you (the narrator is in doubt, perhaps these are the words) Bilal’s call to prayer should not prevent a man from his pre-dawn meal (suhoor), because he gives the call to prayer (the narrator is in doubt, perhaps these are the words) to announce, so that the one performing voluntary prayers may leave them and return for the pre-dawn meal, and so that he may awaken the one who is sleeping among you.”The Prophet Muhammad (peace and blessings be upon him) said:“True dawn does not appear like this or like this”—the Prophet (peace be upon him) struck his hand and raised it—“rather, it appears like this”—the Prophet (peace be upon him) spread his fingers and said this.
