Ikrimah and Abdullah bin Abi Mulaykah (may Allah have mercy on them both) said: We heard Sayyidah Aishah (may Allah be pleased with her) say that the Messenger of Allah (peace and blessings be upon him) passed by the cooking pot, took a bone with meat on it from it and ate, then went to the prayer, and he neither performed ablution nor rinsed his mouth.
