And from his own narration on the authority of Ibn 'Abbas that he said in the explanation of the saying of Allah, Exalted is He, (Alif. Lam. Ra.): '(Alif. Lam. Ra.) Allah says: I am Allah, I see what you do and what you say. That which Muhammad (pbuh) recites unto you is My speech; it is also said that (Alif. Lam. Ra. ) is an oath that Allah swore by. (These are verses of the Scripture that maketh plain) this surah, or verses of the Qur'an, expounds the lawful and unlawful, the commands and prohibitions.
