72:16
وَأَلَّوِ ٱسْتَقَـٰمُوا۟ عَلَى ٱلطَّرِيقَةِ لَأَسْقَيْنَـٰهُم مَّآءً غَدَقًا
wa-allawi is'taqāmū ʿalā l-ṭarīqati la-asqaynāhum māan ghadaqan
If they had taken to the right way, We would have given them abundant water to drink-
If they (non-Muslims) had believed in Allâh, and went on the Right Way (i.e. Islâm) We would surely have bestowed on them water (rain) in abundance.
