Is it permissible to purchase a plot of land through a Murabaha system from an Islamic bank in Jordan, knowing that the bank stipulates the signing of a promise to purchase that includes a clause obliging the buyer to sign an addendum to the promise within three days of the bank’s ownership of the land, and is this transaction considered a stratagem and does it take the ruling of usury if it is not sound, and what are the necessities that permit it?

As long as the bank is Islamic and the transaction is permissible, and the bank will purchase the land so it enters into its possession and responsibility before selling it to you, then there is no objection to the transaction. The existence of the promise to purchase and signing it does not affect this, as it is religiously binding unless there is a valid excuse, especially if retracting from it would harm the bank, according to the resolution of the Islamic Fiqh Academy.
