Q 13:1

بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ In the Name of Allah, the Most Gracious, the Most Merciful المر ۚ تِلْكَ آيَاتُ الْكِتَابِ ۗ وَالَّذِي أُنزِلَ إِلَيْكَ مِن رَّبِّكَ الْحَقُّ وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يُؤْمِنُونَ (1. Alif Lam-Mim Ra. These are the verses of the Book (the Qur'an), and that which has been revealed unto you from your Lord is the truth, but most men believe not.) The Qur'an is Allah's Kalam (Speech) We talked before, in the beginning of Surat Al-Baqarah (chapter 2) about the meaning of the letters that appear in the beginnings of some chapters in the Qur'an. We stated that every Surah that starts with separate letters, affirms that the Qur'an is miraculous and is an evidence that it is a revelation from Allah, and that there is no doubt or denying in this fact. This is why Allah said next, تِلْكَ آيَاتُ الْكِتَابِ (These are the verses of the Book), the Qur'an, which Allah described afterwards, وَالَّذِي أُنزِلَ إِلَيْكَ (and that which has been revealed unto you), O Muhammad, مِن رَّبِّكَ الْحَقُّ (from your Lord is the truth,) Allah said next, وَلَٰكِنَّ أَكْثَرَ النَّاسِ لَا يُؤْمِنُونَ (but most men believe not.) just as He said in another Ayah, وَمَا أَكْثَرُ النَّاسِ وَلَوْ حَرَصْتَ بِمُؤْمِنِينَ (And most of mankind will not believe even if you desire it eagerly.)[12:103] Allah declares that even after this clear, plain and unequivocal explanation (the Qur'an), most men will still not believe, due to their rebellion, stubbornness and hypocrisy.
