الٓمٓر ۚ تِلْكَ ءَايَٰتُ ٱلْكِتَٰبِ ۗ وَٱلَّذِىٓ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ ٱلْحَقُّ وَلَٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يُؤْمِنُونَ
Alif, Lam, Meem, Ra. These are the verses of the Book; and what has been revealed to you from your Lord is the truth, but most of the people do not believe.
We have spoken about similar phrases at the beginning of Sūrah Al-Baqarah. These sublime verses in this Sūrah, and the Qur’ān that God has revealed to you - O Messenger - is the truth in which there is no uncertainty. There is no doubt that it is from God, but most people do not believe in it due to stubbornness and pride.
