Surah 70. Al-Ma'arij, Ayah 40

I.e., of all the variation, throughout the solar year, of the points at which the sun "rises" and "sets": thus stressing the fact that He is the Ultimate Cause of all orbital movement in the universe and, hence, its Creator (cf. 37:5 and 55:17 ).

 The daily points of sunrise and sunset, caused by the earth’s rotation around its own axis.

For the form of adjuration, cf. lxix. 38, n. 5665; also lvi. 75. Here the witness placed before us by Allah is His own power and glory manifested in the splendour of sunrise and sunset at different points through the solar year.

See n. 4034 to xxxvii. 5. If Allah has such power in the wonderful phenomena of the rising of the sun at varying points, repeated year after year, can you not see that He can easily substitute better men than you Unbelievers and blasphemers?

The transition from the singular "I" to the plural "We" may be noted. See n. 56 to ii. 38.
