Is it permissible to sell prepaid cards in installments at an increased price, with a fee for drafting the contract, and to cooperate with other offices in their sale and purchase? Is it permissible to buy cards from the market to cover a deficit? Does the capital integrated into the partnership affect the legal ruling?

It is permissible to sell cards for more than their value, whether in cash or installments. Cooperating with offices to sell them is also permissible after possessing them, provided that there is no prior collusion to circulate them through buying and selling as a stratagem against Islamic law. However, securing and purchasing the remaining cards before concluding the contract with the requester is not permissible. It is permissible for offices to purchase cards after knowing that there is a demand for them. Combining partners' funds is permissible.
