Chapter: The deals done by a weak-minded or an extravagant person

A man was often cheated in buying. The Prophet (ﷺ) said to him, "When you buy something, say (to the seller), No cheating." The man used to say so thenceforward.

A man manumitted a slave and he had no other property than that, so the Prophet (ﷺ) canceled the manumission (and sold the slave for him). Nu'aim bin Al-Nahham bought the slave from him.
