2:2; 3:2; 13:2; 30:2; 31:2; 32:2.
Commentary:
The present and the following three chapters are headed by the abbreviated letters (مقطعات) Alif Lam Mim. For an explanation and significance of these letters, in fact for all abbreviations placed at the head of any Surah, see note under 2:2 & 19:2. The above three letters stand for انا الله أعلم i.e. I am Allah, the All-Knowing. See also 30:2.
