Exegesis of the verse: ((Alif Lam)) and the discussion of the disjointed letters at the beginnings of the surahs.

I seek refuge in Allah from the accursed Shaytan. In the name of Allah, the Most Gracious, the Most Merciful. No, be patient following what came before it I seek refuge in Allah from the accursed Shaytan. The discussion of the Basmalah, its grammar, meaning, and place, has already been presented. The discussion of the alphabetic letters with which the surahs began has also been presented. It is said that the alphabetic letters with which Allah began some of the surahs are symbols for things, and some exegetes have identified them. It is said that they are letters whose meaning we do not know, and Allah knows best what He intended by them. It is said, rather, that they are alphabetic letters with no meaning, and this is the correct view. This is because this Qur'an was revealed in the clear Arabic language, and the Arabic language does not assign a meaning to these alphabetic letters. If it does not assign them a meaning, then by virtue of its revelation in that language, they should have no meaning. However, the scholars said that they have a purpose, meaning that these letters have a purpose: that this Qur'an, which baffled the eloquent Arab orators, was composed of the letters they know and use to construct their speech, and yet it baffled them. That is, if it had come in a non-Arabic language, they would have said they were unable to deal with it, but it came in the Arabic language in which they construct their speech using the letters with which this Qur'an was composed. For this reason, you will hardly find a surah beginning with these alphabetic letters without the mention of the Qur'an following it. This is as stated by al-Zamakhshari, Shaykh al-Islam Ibn Taymiyyah, and a group of scholars.
