Once Hazrat Umme Salama the wife of the Prophet (S.A.W), received some meat from somewhere as a gift. The Prophet (S.A.W) was fond of meat, so she asked maid to keep it for him. In the meantime a beggar came to the door and asked for something in alms.
Hazzarat Umme Salama sought blessings for him which meant that there was nothing to give. The beggar went away. After sometime the Holy Prophet (S.A.W) came and asked HAzrat Umme Salama 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 stone was found there. The whole incident was brought to the knowledge of the Prophet (S.A.W). The prophet (S.A.W) replied that because the meat was not given to a needy person it had turned into stone.
The Shape of the meat changed because it was not given in the name of Allah to a needy person. It happened in the household of the Prophet (S.A.W). Those of us who possess and even then refuse to give to the poor and needy persons, are eating stones and thus our hard heartedness grows day by day. The incident is a lesson for the followers of the Holy Prophet (S.A.W).
