39. The word used for this wind is aqim, which is used for a barren woman, though literally it means dry. If the literal meaning is taken it would mean that it was such an intensely hot and dry wind that whatever it blew on, it caused it to become absolutely dry; and if it is taken in the idiomatic sense it would mean that like a barren woman it was a wind without any benefit: neither it was pleasant, nor it brought rain, nor fertilized the trees, nor contained any other benefit for which the wind blows. At other places it has been stated that this wind was not only useless and dry but it blew so violently that it swept the people off the ground and it continued to rage for eight days and seven nights continuously, till it laid the entire land of the Aad to a waste. (For explanation, see ( E.Ns 20, 21 of Surah HaMim As-Sajdah), and ( E.Ns 25 to 28 of Surah Al-Ahqaf).
40. The commentators have disputed as to which respite it implies. Qatadah says that it alludes to that verse of Surah Houd in which it has been stated that when the Thamud killed the she camel of the Prophet Salih (peace be upon him), they were warned by Allah that they had three more days to enjoy life after which they would be overtaken by the torment. Contrary to this, Hasan Basri has expressed the opinion that this thing had been said by the Prophet Salih (peace be upon him) to his people in the beginning of his mission and by this he meant that if they would not adopt the way of repentance and faith, they would be granted a respite to enjoy life in the world only till an appointed time, and then they would be overtaken by the torment. The second of these two commentaries seems to be more correct, for the following verse (But they defied the command of their Lord) indicates that the respite being mentioned here had been given before the defiance and they committed it after the warning. On the contrary, the three days respite mentioned in Surah Houd had been given after the wicked people had committed the final defiance which became decisive in their case and sealed their doom forever afterwards.
41. Different words have been used for this torment at different places in the Quran. Somewhere it has been called rajafah (a frightful and shocking calamity), somewhere saihah (a crashing and thundering disaster), somewhere taghiyah (a most severe affliction) and here it has been described as saiqah (a calamity that strikes like a thunderbolt). Probably this torment was like an earthquake which was also accompanied by a terrible noise.
42. Intisar from which the word muntasirun in the original is derived means to save oneself from an attack by somebody as well as to avenge oneself on the attacker.
