Tafsir of Ar-Ra'd 13:1

The Qur'an is Allah's Kalam (Speech) Allah said:

المر

Alif Lam-Mim Ra We talked before, in the beginning of Surah Al-Baqarah about the meaning of the letters that appear in the beginnings of some Surahs 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,

تلك آيات الكتاب

These are the verses of the Book, the Qur'an, which Allah described afterwards,

والذي أنزل إليك

and that which has been revealed unto you, (O Muhammad),

من ربك الحق

from your Lord is the truth, Allah said next,

ولكن أكثر الناس ﻻ يومنون

but most men believe not. just as He said in another Ayah,

وما أكثر الناس ولو حرصت بمومنين

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
