Surah Al-Fath, Verse 12

بَلۡ ظَنَنتُمۡ أَن لَّن يَنقَلِبَ ٱلرَّسُولُ وَٱلۡمُؤۡمِنُونَ إِلَىٰٓ أَهۡلِيهِمۡ أَبَدٗا وَزُيِّنَ ذَٰلِكَ فِي قُلُوبِكُمۡ وَظَنَنتُمۡ ظَنَّ ٱلسَّوۡءِ وَكُنتُمۡ قَوۡمَۢا بُورٗا١٢

bal ẓanantum an lan yanqaliba l-rasūlu wal-mu'minūna ilā ahlīhim abadan wazuyyina dhālika fī qulūbikum waẓanantum ẓanna l-sawi wakuntum qawman būran

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."
