Financial investment transactions in Islamic banks

In the jurisprudence of financial transactions, which is considered a priority research area in Islamic economics, due to the widespread affliction among Muslim countries with many prohibited transactions such as usury, deception, and uncertainty, and the suspension of many contracts that represent the spirit of Islamic economy such as partnerships and ventures, and at the same time calling for the creation of a legitimate alternative in real life, all of this necessitates a scientific systematic approach that combines the objectives of Shariah in economic life with applicability in reality. The process of evaluating an institution requires establishing a set of criteria, foremost among them being methodological standards to measure the extent of commitment to the adopted approach, its principles, and constants. This leads to the sound judgment of the bank under study using this methodology in its investment financial transactions, as it bears the responsibility as an Islamic bank to implement Shariah completely and comprehensively in all its transactions, which makes it an Islamic institution capable of defending its existence, proving its ability to compete well, and achieving the legally considered interest for all people, especially in this brief time span of the lifespan of institutions in general and financial and banking institutions in particular.
