Al-Mukhtasar
وَكَذَٰلِكَ أَوْحَيْنَآ إِلَيْكَ رُوحًا مِّنْ أَمْرِنَا ۚ مَا كُنتَ تَدْرِى مَا ٱلْكِتَـٰبُ وَلَا ٱلْإِيمَـٰنُ وَلَـٰكِن جَعَلْنَـٰهُ نُورًا نَّهْدِى بِهِۦ مَن نَّشَآءُ مِنْ عِبَادِنَا ۚ وَإِنَّكَ لَتَهْدِىٓ إِلَىٰ صِرَٰطٍ مُّسْتَقِيمٍ ﴿٥٢﴾
Just as I sent revelation to the prophets before you, O Messenger, I revealed to you a Qur’ān from Me. Prior to it you did not know about the heavenly scriptures revealed to the messengers, and you did not know what is faith? But I revealed this Qur’ān as a light by which I guide whomever of My servants I wish. You show people a straight path, which is the religion of Islam.
