Yazid bin Zari' يزيد بن زريع · Wages (Kitab Al-Ijarah)

Muhayyisah asked permission of the Messenger of Allah (ﷺ) regarding hire of the cupper, but he forbade him. He kept on asking his permission, and at last he said to him: Feed your watering camel with it and feed your slave with it.

The Prophet (ﷺ) Said: The children of a man come from what he earns, rather they are his pleasantest earning; so enjoy from their property. Abu Dawud said: Hammad b. Abi Sulaiman added in his version: "When you need." But this (addition) is munkar (not authoritative).

Hind came to the Prophet (ﷺ) and said: Messenger of Allah, Abu Sufyan is a stingy person. Is there any harm to me if I spend on his dependants from his property without his permission ? The Prophet (ﷺ) replied: There is no harm to you if you spend according to the custom.

The Prophet (ﷺ) as saying: One who seeks to take back a gift like the one who returns to it vomit. Hammam said: "And Qatadah said: We regard vomiting as unlawful."
