Sayyidah Umm Salamah (may Allah be pleased with her) said: The Prophet (peace and blessings be upon him) came to me and the colour of his face had changed. I thought it was because of illness. I said: Why has the colour of your face changed? He (peace and blessings be upon him) said: "Because of the seven dinars that came yesterday and which we have not distributed, and they are lying in the bed."
