The Word of your Lord (which He sent down in parts in different periods considering the conditions of each period) is perfected (with the Qur’an) as the embodiment of truth (with respect to the essentials of belief, principles of worship and good conduct, the rules to govern human life, and all the tidings it gives considering the past and future including the Hereafter), and of justice (regarding all the commandments it contains): there is no altering of His words (the laws He has established for life, and the operation of the universe; attempting to interfere with them will bring about great disasters, so no one must ever attempt to change His commandments, which are contained in the Book). He is the All-Hearing, the All-Knowing (Who knows every need of every creature, every requirement of every age, just as He knows how you respond to His commandments).
