Allah states that He sent His Messenger Muhammad ﷺ with the guidance and the religion of truth to all the people of the earth, the Arabs and non-Arabs, lettered and unlettered. Allah also states that He sent Muhammad with clear evidences and the distinction between truth and falsehood. Allah said,

يَـأَهْلَ الْكِتَـبِ قَدْ جَآءَكُمْ رَسُولُنَا يُبَيِّنُ لَكُمْ كَثِيراً مِّمَّا كُنتُمْ تُخْفُونَ مِنَ الْكِتَـبِ وَيَعْفُواْ عَن كَثِيرٍ

(O People of the Scripture! Now has come to you Our Messenger explaining to you much of that which you used to hide from the Scripture and passing over much.) So the Prophet explained where they altered, distorted, changed and lied about Allah. He also ignored much of what they changed, since it would not bring about any benefit if it was explained. In his Mustadrak, Al-Hakim recorded that Ibn `Abbas said, "He who disbelieves in stoning (the adulterer to death) will have inadvertently disbelieved in the Qur'an, for Allah said,

يَـأَهْلَ الْكِتَـبِ قَدْ جَآءَكُمْ رَسُولُنَا يُبَيِّنُ لَكُمْ كَثِيراً مِّمَّا كُنتُمْ تُخْفُونَ مِنَ الْكِتَـبِ

(O People of the Scripture! Now has come to you Our Messenger explaining to you much of that which you used to hide from the Scripture) and stoning was among the things that they used to hide." Al-Hakim said, "Its chain is Sahih, and they did not record it." Allah next mentions the Glorious Qur'an that He sent down to His honorable Prophet ,

قَدْ جَآءَكُمْ مِّنَ اللَّهِ نُورٌ وَكِتَـبٌ مُّبِينٌيَهْدِى بِهِ اللَّهُ مَنِ اتَّبَعَ رِضْوَانَهُ سُبُلَ السَّلَـمِ

(Indeed, there has come to you from Allah a light and a plain Book. Wherewith Allah guides all those who seek His pleasure to ways of peace.) meaning, ways of safety and righteousness,

وَيُخْرِجُهُمْ مِّنِ الظُّلُمَـتِ إِلَى النُّورِ بِإِذْنِهِ وَيَهْدِيهِمْ إِلَى صِرَطٍ مُّسْتَقِيمٍ

(and He brings them out of darkness by His permission unto light and guides them to a straight path.) He thus saves them from destruction and explains to them the best, most clear path. Therefore, He protects them from what they fear, and brings about the best of what they long for, all the while ridding them of misguidance and directing them to the best, most righteous state of being.
