Surat Al-Fath (The Victory) - الفتح

بَلْ ظَنَنتُمْ أَن لَّن يَنقَلِبَ ٱلرَّسُولُ وَٱلْمُؤْمِنُونَ إِلَىٰٓ أَهْلِيهِمْ أَبَدًا وَزُيِّنَ ذَٰلِكَ فِى قُلُوبِكُمْ وَظَنَنتُمْ ظَنَّ ٱلسَّوْءِ وَكُنتُمْ قَوْمًۢا بُورًا ﴿١٢﴾

Nay! you rather thought that the Apostle and the believers would not return to their families ever, and that was made fairseeming to your hearts and you thought an evil thought and you were a people doomed to perish.
