Securitization involves pooling various financial assets and issuing securities backed by those assets. There are several types of Islamic securitization, including those based on musharakah, murabahah, and ijarah contracts. Musharakah certificates represent direct ownership in the securitized assets. Murabahah contracts cannot be securitized to create negotiable instruments since the amount must be transferred at par value. Ijarah certificates represent proportionate ownership of the leased asset.
