The party who seeks liquidity from entering into a tawarruq (Islamic monetization). In Arabic script, mutawarriq is written:

متورّق (جمع: متورقون ومتورقين)

More specifically, mutawarriq may be a customer who purchases a commodity from an Islamic bank and sells it to a third party to obtain liquidity. Mutawarriq could also be an Islamic bank or financial institution which purchases a commodity from a customer or another institution and sells it to a third party to obtain liquidity. It is up to mutawarriq to sell the commodity for whatever spot (cash) price. That means the resale price may be higher, lower, or equal to the original purchase price.
