On the one hand, it is very difficult to maintain economic order in the current world, regardless of the penalty for delay, and on the other hand, the suspicion that the legal institution is illegal and the need to comply with the rules of law according to the fourth principle of the Constitution of the Islamic Republic Iran demands more and more exploration around this issue. After the revolution, the jurists of the Guardian Council, according to the fourth principle of the constitution, declared that their duty to implement the laws in accordance with Anwar Sharia was illegal and haram, but later due to increasing liquidity and rising inflation. The Guardian Council was forced to reconsider and accept the compensation for the delay, but doubts remained. To seek a solution in the Shari'a, and by determining the damages on the delay of payment, to establish a lever for the fulfillment of the obligation on time.
