What is the ruling on refraining from paying rent on the pretext of the lessor's corruption and his exaggeration in [charging] interest, and must the unpaid amount be estimated and paid?

The tenant must fulfill the terms of the lease contract and pay the full rent to the landlord without delay, because it is a debt upon him, and the procrastination of the wealthy is injustice. The corruption or disbelief of the landlord has no bearing on the payment of the rent due to him, because the Muslim is commanded to fulfill rights and abide by contracts with all people.
