قَالُوا۟ سُبْحَٰنَكَ مَا كَانَ يَنۢبَغِى لَنَآ أَن نَّتَّخِذَ مِن دُونِكَ مِنْ أَوْلِيَآءَ وَلَٰكِن مَّتَّعْتَهُمْ وَءَابَآءَهُمْ حَتَّىٰ نَسُوا۟ ٱلذِّكْرَ وَكَانُوا۟ قَوْمًۢا بُورًۭا
They will say: Be Thou Glorified! it was not for us to choose any protecting friends beside thee; but Thou didst give them and their fathers ease till they forgot the warning and became lost folk.
