Surah 51. Az-Zariyat, Ayah 41

 lit., ‘a barren wind,’ since the wind was not productive—it did not carry rain or fertilize trees.

Cf. xlvi. 21-26. The point here is that the 'Ad were a gifted people: Allah had given them talents and material wealth: but when they defied Allah, they and all their belongings were destroyed in a night, by a hurricane which they thought was bringing them the rain to which they were looking forward. How marvellously Allah's Providence works, to help the good and destroy the wicked!
