It is narrated from Sayyidah Umm Ayman (may Allah be pleased with her) that she sifted flour and made a loaf of bread from it for the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) asked: "What is this?" She said: This is a food we make here, and I wished to make a loaf of it for you. He (peace and blessings be upon him) said: "Put it back into the flour, then knead it."
