It is narrated from Hazrat Anas (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him) said to me, "O Anas! I intend to fast, give me something to eat." I brought some dates and a vessel of water. By that time, Hazrat Bilal (may Allah be pleased with him) had already given the call to prayer. The Prophet (peace and blessings be upon him) said, "Anas! Find someone who can join me in eating." So I went and brought Hazrat Zaid bin Thabit (may Allah be pleased with him). He said, "O Messenger of Allah (peace and blessings be upon him)! I have drunk a drink of sattu and I intend to fast." The Prophet (peace and blessings be upon him) said, "I also intend to fast." Then both of them ate suhoor together. After that, the Prophet (peace and blessings be upon him) prayed two rak'ahs and went out, and the prayer had been established.
