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 little thanks for this. Allah said in another Ayah,

[وَإِن تَعُدُّواْ نِعْمَةَ اللَّهِ لاَ تُحْصُوهَا إِنَّ الإنْسَانَ لَظَلُومٌ كَفَّارٌ]

(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]

[وَلَقَدْ خَلَقْنَـكُمْ ثُمَّ صَوَّرْنَـكُمْ ثُمَّ قُلْنَا لِلْمَلَـئِكَةِ اسْجُدُواْ لأَدَمَ فَسَجَدُواْ إِلاَ إِبْلِيسَ لَمْ يَكُن مِّنَ السَّـجِدِينَ ]

(11. And surely, We created you and then gave you shape; then We told the angels, "Prostrate yourselves to Adam,'' and they prostrated, except Iblis (Shaytan), he refused to be of those who prostrated.)
