It is narrated from Hazrat Abdullah bin Harith (may Allah be pleased with him) that: A man passed by a group of people among whom the Prophet (peace and blessings be upon him) was also present. He had a piece of cloth, for which he stated a price higher than its actual value. The narrator says it was a sheet. Some people from the group asked him: For how much are you selling it? I think he stated a price higher than its value. Then he said that he had lied. The Messenger of Allah (peace and blessings be upon him) was also among them. Then he returned and submitted, "O Messenger of Allah (peace and blessings be upon him)! I sold it for such and such an amount, which was more than its actual value." The Prophet (peace and blessings be upon him) said: "Whatever extra you have received, give it in charity."

It is narrated from Hazrat Ibn Umar (may Allah be pleased with them both) that if a slave is jointly owned by two persons and one of them sets him free, then it is obligatory upon him to also free the remaining part of the slave (by purchasing it). If he does not possess anything, then the slave should work to free himself in exchange for his own neck. Then both of them will share in the slave’s allegiance (wala’).
