إِنَّ ٱلدِّينَ عِندَ ٱللَّهِ ٱلْإِسْلَٰمُ ۗ وَمَا ٱخْتَلَفَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ إِلَّا مِنۢ بَعْدِ مَا جَآءَهُمُ ٱلْعِلْمُ بَغْيًۢا بَيْنَهُمْ ۗ وَمَن يَكْفُرْ بِـَٔايَٰتِ ٱللَّهِ فَإِنَّ ٱللَّهَ سَرِيعُ ٱلْحِسَابِ
3:86.
Important Words:
اسلام (complete submission) which is derived from اسلم which again is derived from سلم signifies: (1) complete submission to God; (2) the religion of Islam, the latter meaning being also based on the first-mentioned meaning (Taj). See also 2:113.
Commentary:
The verse throws light on the fact that though other religious systems also claim to inculcate belief in the Oneness of God and submission to His will, yet it is only in Islam, the religion brought by the Holy Prophet, that the idea of submission to God’s will has found its consummation; for complete submission requires complete manifestation of God’s attributes and it is in Islam alone that such manifestation has taken place. So Islam alone of all religious systems deserves to be called the religion of God in the real sense of the term. All true religions were indeed more or less Islam in their original form and their adherents Muslims in the literal sense of the term, but not till the time when religion became complete in all its different aspects was any faith given the name of Islam, which was reserved for the final dispensation perfected in the Quran.
The clause, And those who were given the Book did not disagree but after knowledge had come to them, out of mutual envy, signifies that if Jews and Christians had been truly submissive to the will of God, as they claim to be, they would not have refused to accept Islam, which is submission to Divine will in its completest and most perfect form. By their rejection of Islam they have brought ruin upon themselves and have been deprived of God’s grace and bounties of which they had had an ample share before.

All true religions were indeed more or less Islam in their original form and their adherents Muslims in the literal sense of the term, but not till the time when religion became complete in all its different aspects was it given the name of Al-Islam, which was reserved for the final Dispensation perfected in the Qur’an. The verse further explains 2:63.
