Some assert, what has the Quran brought? Nothing more than what is already contained in the Torah. It is this very misconception which has moved certain Christians to write treatises on the uselessness of the Holy Quran. If only they had partaken of true wisdom and real insight, they would not have gone astray. Such people state that the Torah forbids one to commit adultery and likewise, the Quran too forbids adultery. The Quran teaches the Unity of God and the Torah also teaches a person to worship the One God. So what then is the difference? At face value, this seems like a complicated question. If this question was posed to an uninformed person, he would be flustered. In actual fact, intricate and twisted questions like these can only be resolved by the special grace of Allah Almighty. It is these very Quranic insights, which are revealed at their appropriate time. In reality, there is definitely a similarity between the Holy Quran and the Torah – we do not deny this. However, the Torah has only presented a mere text without any argumentation, proof or commentary. However, the Holy Quran takes a rational approach on all matters. This is because the faculties of the people of that time possessed an uncultivated nature. And so, the Quran adopted the practice of expounding the benefits of worship and morality. Moreover, it not only puts forth the benefit, but rather presents them with the support of argumentation and proof in a rational manner, so that those who possess a sound intellect are left with no room for denial. As I have just mentioned, in the time of the Quran, faculties were bent towards rationality, whereas in the time of the Torah, a more primitive state existed. From the time of Adamas, humans continued to develop and when the Quran appeared, this development had reached its completion, in the likeness of a circle. It is related in the Hadith that the age assumed the form of a “full circle”. Allah the Exalted states:
مَا کَانَ مُحَمَّدٌ اَبَاۤ اَحَدٍ مِّنۡ رِّجَالِکُمۡ وَ لٰکِنۡ رَّسُوۡلَ اللّٰہِ وَ خَاتَمَ النَّبِیّٖنَ
“Muhammad is not the father of any of your men, but he is the Messenger of Allah and the Seal of the Prophets.” Necessity is the engine that fuels prophethood, as it were. Dark nights draw in the light that delivers the world from darkness. It was due to this need that the system of prophethood began, and upon reaching the era of the Quran, it attained to completion. Now every need has been fulfilled. This establishes that the Holy Prophet, peace and blessings of Allah be upon him, was the Seal of the Prophets. Indeed, one significant and evident hallmark of this is that the Quran presents reasoned argumentation, while the Torah has not done so even to a minor degree.
