وَلَوْ أَنَّ أَهْلَ ٱلْقُرَىٰٓ ءَامَنُوا۟ وَٱتَّقَوْا۟ لَفَتَحْنَا عَلَيْهِم بَرَكَٰتٍۢ مِّنَ ٱلسَّمَآءِ وَٱلْأَرْضِ وَلَٰكِن كَذَّبُوا۟ فَأَخَذْنَٰهُم بِمَا كَانُوا۟ يَكْسِبُونَ
And if the people of the townships had believed and kept from evil, surely We should have opened for them blessings from the sky and from the earth. But (unto every messenger) they gave the lie, and so We seized them on account of what they used to earn.
