It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Eating suhoor is a source of blessing, so do not abandon it, even if you only drink a sip of water. For Allah and His angels send mercy, each in their own way, upon those who partake in suhoor.
