وَأَن لَّوِ اسْتَقَامُوا عَلَى الطَّرِيقَةِ لَأَسْقَيْنَاهُم مَّاءً غَدَقًا (16)
(72:16) If *15 people were to keep firmly to the Right Way, We would have vouchsafed them abundant rain *16
*15) The conversation of the jinn having come to an end, with this begins the speech of Allah.
*16) This is the same thing as has been said above in Surah Nuh: 10-11. "Seek forgiveness of Allah. .. He will send abundant rains for you from heaven. " (For explanation, see E.N. 12 of Surah Nuh). Abundance of water has been used for abundance of blessings metaphorically for human life and habitation depend on water. Without water there can be no human settlement, nor can man's basic needs be fulfilled, nor his industries work and prosper.
