A man came to the Prophet, Allah’s blessings be upon him and his Family, and said: O Messenger of Allah, I have taught my son this book, so for what thing shall I give it? He said: Give it, for the sake of Allah, to your father, and do not give it to five: do not give it to an evil-wisher, nor a goldsmith, nor a slaughterer, nor a wheat seller, nor a slave trader. Then he said: O Messenger of Allah, and what is an evil-wisher? He said: The one who sells winding sheets and wishes for the death of my nation, whereas the one born from my nation is more beloved to me than what the sun has shined upon. As for the goldsmith, he treats the fraud of my nation. As for the slaughterer, he slaughters until mercy departs his heart. As for the wheat seller, he corners food from my nation, whereas for a servant to meet Allah as a thief is more beloved to me than if he meets Him having cornered food for forty days. As for the slave trader, indeed, Jibra’eel, peace be upon him, came to me and said: O Muhammed, indeed, the evil ones from your nation are those who sell people.
