Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: I heard the Prophet of Allah (peace and blessings be upon him) say: "We, the community of Prophets, have been commanded to hasten our breaking of the fast, to delay our pre-dawn meal (suhur), and to place our right hands upon our left hands in prayer."
