I say, and with God's success: The use of deferred Murabaha has become common in Islamic banks as an alternative to usurious transactions, particularly for traders who wish to purchase certain goods. In the usurious market, it is customary for them to borrow from traditional banks based on interest, and then buy the required goods with the amounts they borrowed from the banks. As for non-usurious banks, instead of lending them cash amounts, they purchase those goods themselves at a spot price, and then sell those goods to them at a higher deferred price. Since customers approach banks requesting that the bank purchase the goods, and then enter into a deferred Murabaha with them, this is called "Murabaha for the buyer's order," as mentioned in the jurisprudence of sales (1: 614). Al-Sarakhsi said in Al-Mabsut (30: 238): "A man instructed another to buy a house for a thousand dirhams, and informed him that if he did so, the instructing party would buy it from him for a thousand and one hundred. The instructed party feared that if he bought it, the instructing party might not want to buy it. He said: He should buy the house on the condition that he has the option for three days and take possession of it, then the instructing party comes to him and says: I have taken it from you for a thousand and one hundred, and the instructed party replies: It is yours for that... And if the instructing party does not wish to buy it, the instructed party can return it on the condition of the option, thus preventing harm to him." It is noted that they have sufficed with mentioning the term of the deferred payment here instead of the binding promise, but since the binding promise has become widely known and established as previously clarified, it can be relied upon, and God knows best.
