Must one compensate one's friends for the broker's share of the down payment for a lease agreement that was not finalized?

The broker's commission is shared among everyone and divided equally, with each person bearing their share. You must return the share of your friends who paid it on your behalf.

Fulfilling covenants, agreements, and promises is among the important virtues in Islam. The Messenger of Allah, peace and blessings be upon him, warned us against breaking promises and considered it a trait of hypocrisy.
