“Whatever it is about which you differ, its judgment rests with Allah” (al-Shūrā 42:10).

This verse refutes all those who charge the Islamic sharīʿah with deficiency or shortcoming—whether they are atheists, heretics, or the half-educated whose limited understanding prevents them from perceiving the depths of this Law, so they attribute their own inadequacy to it. It stands as a rebuttal to anyone who claims that the sharīʿah is incomplete, that it fails to meet people’s needs and secure their interests until the Day of Resurrection, or that it was meant only for the first era. Many ignorant individuals, when a legal ruling is presented to them, retort, “That applied in the Prophet’s time, in the early days; conditions have changed and circumstances are different now. Those rulings were for people who have long passed away and for problems that no longer exist.” Such talk amounts to disbelief in Allah and a denial of His words: “Today I have perfected your religion for you” (al-Māʾidah 5:3). Allah perfected this religion for this ummah until the Hour is established—for every time, every place, and every generation.

The verse likewise refutes the innovators who devise acts of worship of their own making, attribute them to the religion, and yet have no evidence for them from the Book of Allah or the Sunnah of His Messenger ﷺ.
