[Pooya/Ali Commentary 91:1] For verses 1 to 6 see commentary of Muddaththir: 32 to 35 for calling in evidence the signs which manifest Allah's glory, wisdom and might in nature by which the cosmic harmony is maintained. So far man's knowledge about the physical aspects of the sun is limited, but there is no doubt that it is a source, of light for us. The moon follows or acts as substitute to the sun for illuminating our world with reflected light and therefore may be called the sun's vicegerent. Aqa Mahdi Puya says: Tala means to follow a thing or person as a principal source in consequence of total adherence. The follower derives his strength from him who is followed. See commentary of Hud: 17. Some commentators say that the sun stands for the Holy Prophet and the moon represents All ibn abi Talib. Day and night are periods of time. The day reveals the sun's glory and the night conceals it from our sight according to our subjective reception of light, but the light is there, all the time. As the night ends, the sleeping creatures are once again resurrected. One day Allah shall bring about the final sleep (death) after which the final day of resurrection shall appear. The regulated harmony in the outer space controlled by the omnipotent will of Allah gives us rain, one of many known benefits available to man, and then the earth gives food to all the created beings. In addition to food there are rivers, oceans, mountains, valleys and several types of minerals etcetera, in the wide expanse of the earth which serve man and other created beings in many ways. Verses 7 and 8 refer to the soul of man, with its capabilities and faculties, endowed with the power of distinguishing between good and evil, right and wrong. See commentary of Balad: 8 to 20. Then the conclusion is stated in verses 9 and 10 that he who purifies himself achieves success (see commentary of Muminum: 1 to 10); and he who corrupts it fails and becomes a loser.

[Pooya/Ali Commentary 91:11] See commentary of Araf: 73 to 79 and Hud: 61 to 68 for the people of Thamud who had corrupted their souls as pointed out in verse 10, hamstrung the she-camel appointed as a sign of Allah by prophet Salih to test their faith and belied him as a false prophet.

[Pooya/Ali Commentary 91:14] (see commentary for verse 11)

[Pooya/Ali Commentary 91:15] Allah decreed the total destruction of the Thamud. Any such destruction of men and material may be considered a loss from the point of view of human beings because the community would be deprived of manpower and resources, but as Allah is the creator and can create at will there can be no question of any such apprehension in His case..
