Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "We are a group of Prophets (peace be upon them all), we have been commanded to hasten in breaking the fast (at the time of iftar), to delay the pre-dawn meal (suhoor), and that we should hold our left hands with our right hands during prayer."
