What is the religious ruling on selling credit to the bank, receiving its price from them, and giving the beneficiary the credit?

For a murabaha (cost-plus financing) transaction to be valid, the bank must purchase and take possession of the commodity before selling it to the beneficiary, based on the Prophet's (peace be upon him) saying: "Do not sell what you do not possess," and his saying: "If you buy a commodity, do not sell it until you take possession of it." He (peace be upon him) also forbade "that goods be sold where they are bought until merchants transport them to their own places."

Therefore, if the "balance" refers to a telecommunications balance, it must first be transferred to the bank, and then the bank sells it to the beneficiary, because a balance is considered movable property. Possession of movable property occurs by taking hold of it and removing it from the seller's premises. The preponderant opinion is that possession is a prerequisite for all commodities, and that possession of movable property only occurs by moving it, to prevent deception and superficiality. Thus, it is not permissible for the bank to sell the balance while it is in the beneficiary's account; rather, it must be transferred to the bank before being sold.
