Sayyidah Umm Ishaq al-Ghanawiyyah (may Allah be pleased with her) narrated: We were with the Messenger of Allah (peace and blessings be upon him) when a bowl of tharid was brought. The Messenger of Allah (peace and blessings be upon him) ate, and I ate with him (peace and blessings be upon him), and Dhu al-Yadayn (may Allah be pleased with him) also ate with us. Then the Messenger of Allah (peace and blessings be upon him) picked up a bone with meat on it and was about to give it to me, and he said: "What is the matter with you?" I said: I was fasting but I forgot. Dhu al-Yadayn (may Allah be pleased with him) said: Now, after you have eaten your fill? The Messenger of Allah (peace and blessings be upon him) said: "There is no harm on you; it was only provision that Allah sent to you, so now complete your fast."
