He was also asked:

A man leased out land forming part of his land grant for a specified term. The lessee took possession of the land, and the lessor received part of the rent. The lessee then recovered the rent he had paid to the lessor and terminated the lease. He subsequently stated that he had ploughed part of the land and demanded that the lessor pay for the ploughing. Is the lessor entitled to an amount equivalent to the cost of ploughing merely on the lessee’s statement, or not? May the lessor rescind the lease without a valid basis in Islamic law?

He replied:

If the lessee rescinded the lease after taking possession of the land, then, provided that they mutually agreed to cancel the lease or that he rescinded it on valid grounds, he must pay rent proportionate to the duration of his possession of the land, and he is entitled to the customary value of his ploughing.

He—may Allah have mercy on him—was asked:

Concerning the trustee of an endowment or an orphan’s property: may he hand over premises belonging to the endowment or the orphan’s property for someone to occupy without a lease valid under Islamic law? And if someone calls witnesses to attest to his declaration that he has leased specified premises from the endowment’s managing agent for a specified term
