Sayyiduna Sufyan bin Abdullah al-Thaqafi (may Allah be pleased with him) narrates: We were in the delegation that came to the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) pitched two tents for us near the house of Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him). Sayyiduna Bilal (may Allah be pleased with him) would bring us our food for breaking the fast, and we would ask: "O Bilal! Has the Messenger of Allah (peace and blessings be upon him) broken his fast?" He would say: "Yes, I only come to you after the Messenger of Allah (peace and blessings be upon him) has broken his fast." Then he would set down the food, and he would eat and we would eat. And Sayyiduna Bilal (may Allah be pleased with him) would also bring us our pre-dawn meal (suhur).
