Allah reminds of His favor on His servants in that He made the earth a fixed place for dwelling, placed firm mountains and rivers on it and made homes and allowed them to utilize its benefits. Allah made the clouds work for them (bringing rain) so that they may produce their sustenance from them. He also created the ways and means of earnings, commercial activities and other professions. Yet, most of them give liltle thanks for this. Allah said in another Ayah,
(And if you count the blessings of Allah,never will you be able to count them. Verily, man is indeed a wrongdoer, an ingrate.) 14:34
