Alif, Lam, Ra. These are the verses of the wise Book (10:1)

Almuntakhab Fi Tafsir Alquran Alkarim

(Alef), L. (Lam), R. (Raa), the Surah opens with these introductory letters from the Arabic Alphabet to draw attention to the miracle of the Quran which though written in the peoples tongue, cannot be emulated. These divine words -the preceding and those to follow- are divinely discoursed, verses, constituting the Book -the Quran- and verses wisdom to divine knowledge

(10:1) Alif. Lam. Ra. These are the verses of the Book overflowing with wisdom. *1

*1). This introductory statement carries a subtle note of warning. For the unbelievers, out of their sheer stupidity looked upon the Qur'an which was presented to them by the Prophet (peace be on him) as merely a literary masterpiece, an embodiment of spellbinding poetic imagination, a fascinating discourse on a very sublime, illusive plane in the manner of soothsayers. The unbelievers are told that such notions are pure misconceptions. On the contrary, the Qur'anic verses are part of a Book which abounds in wisdom. Hence, if they disregard the Qur'an, they are merely depriving themselves of a treasure-house of wisdom.
