This research is an attempt to make a jurisprudential justificatory study. I started with an introduction, in which I explained that the Islamic Religion is based on collecting the interests of creatures, and that its provisions are justified, but some of its causes appeared to us, but others have not appeared to us. We worshiped Allah, to Whom be ascribed all perfection and majesty, by conceding to the order of Allah about them. If this proof ever indicates that the text was mentioned for a certain case or cause, and then that case changed, or that reason, for which the provision was ascribed, fell off, the provision must be changed according to the change of its reason. Here, I quoted the sayings of the senior scholars that supported this meaning.
