بَلْ Nay ظَنَنتُمْ you thought أَن that لَّن (would) never يَنقَلِبَ return ٱلرَّسُولُ the Messenger وَٱلْمُؤْمِنُونَ and the believers إِلَىٰٓ to أَهْلِيهِمْ their families أَبَدًۭا ever وَزُيِّنَ that was made fair-seeming ذَٰلِكَ that was made fair-seeming فِى in قُلُوبِكُمْ your hearts وَظَنَنتُمْ And you assumed ظَنَّ an assumption ٱلسَّوْءِ evil وَكُنتُمْ and you became قَوْمًۢا a people بُورًۭا ruined ١٢
But you thought that the Messenger and the believers would never return to their families, ever, and that was made pleasing in your hearts. And you assumed an assumption of evil and became a people ruined."
