Early performance of contractual obligaition in Islamic and Iranian Law

In contract law, general rule is that contractual obligation must be fulfilled in due date. Any breach of this rule either as a result of a delay or the lack of its implementation requires compensation. Undoubtedly, the time of contract performance is among the factors that has a direct effect on the parties’ liability. Therefore, the obligation must be met in due date within the definite period.  However, there is a possibility that under some circumstances, the performance occurs earlier than due date which is interpreted as an early performance. The question is whether it is possible to perform before the due date. Although some countries have a clear legal position in this regard, Iranian law does not consider early performance. This subject has not discussed by lawyer and academics either. On the other hand, this issue has been dealt with by jurisprudence, and different views have been expressed. There is no stipulated valuation in Iranian Law, we suggest that this issue should be considered in the Civil Code.
