Silsilat al-Ahadith al-Sahihah

Abu Zubair narrates from Sayyiduna Jabir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) passed by a man who was turning about restlessly. He asked about him. The companions said: O Messenger of Allah! He is fasting. The Prophet called him and ordered him to break his fast and said: "Is it not sufficient for you that you are in the company of the Messenger of Allah (peace and blessings be upon him) in the path of Allah, that you also began to fast?"
