Assalamu Alaikum Brothers in Islam,
I found a narration in 'Behasti Zewar' in which there has been narated the following without any credentials or sources.
"Once Hazrat Umme Salma, wife of the prophet Muhammmad( pbuh) received some meat from somewhere as a gift. The Prophet Muhammad was fond of meat, so she decided to keep it for him. In the meantime a beggar came to the door and asked for something in alms.
Hazrat Umme Salma sought blessings for him which meant that there was nothing to give. The beggar went away. After some time Prophet Muhammad came and asked Hazrat Umme Salma for something to eat. She asked the maid to bring the meat. When the maid went to bring the meat it was not on the shelf and in its place a stone was found. The whole incident was brought to the knowledge of the Prophet Muhammad(pbuh). The Prophet replied that because it was not given to a needy person it had turned to stone."
Is this authentic? Please give sources if it is.
