A man came to the Prophet, peace be upon him and his family, and said: "O Messenger of Allah (swt), I have taught my son to read and write. In what profession should I place him?" The Prophet, peace be upon him and his family, replied:"Entrust him to Allah (swt) and do not place him in five professions: Do not make him a seller of shrouds, nor a jeweler, nor a butcher, nor a grain merchant, nor a slave trader." The man asked: "O Messenger of Allah (swt), what is the harm in selling shrouds?" The Prophet, peace be upon him and his family, explained: "The one who sells shrouds wishes for the death of my nation, while the birth of a new soul in my nation is more beloved to me than all that the sun has risen upon. As for the jeweler, he engages in defrauding my nation. As for the butcher, he slaughters so frequently that mercy departs from his heart. As for the grain merchant, he hoards food against my nation, and it is more beloved to me that a servant meets Allah (swt) as a thief than that he meets Him having hoarded food for forty days. As for the slave trader, Archangel Jibril (as) came to me and said: 'O Muhammad, the worst of your nation are those who sell human beings.'"
