صحيح البخاري

Narrated Tawus:

That he was told by the most learned one amongst them (i.e. Ibn `Abbas) that the Prophet (ﷺ) went towards some land which was flourishing with vegetation and asked to whom it belonged. He was told that such and such a person took it on rent. The Prophet (ﷺ) said, "It would have been better (for the owner) if he had given it to him gratis rather than charging him a fixed rent.
