Surah Al-Fat'h (The Victory), Verse 12

بَلْ ظَنَنْتُمْ اَنْ لَّنْ یَّنْقَلِبَ الرَّسُوْلُ وَالْمُؤْمِنُوْنَ اِلٰۤی اَهْلِیْهِمْ اَبَدًا وَّزُیِّنَ ذٰلِكَ فِیْ قُلُوْبِكُمْ وَظَنَنْتُمْ ظَنَّ السَّوْءِ وَكُنْتُمْ قَوْمًا بُوْرًا ۟

Bal zanantum al lany yanqalibar Rasoolu walmu'minoona ilaaa ahleehim abadanw wa zuyyina zaalika fee quloobikum wa zanantum zannnas saw'i wa kuntum qawmam booraa

“"Nay, ye thought that the Messenger and the Believers would never return to their families; this seemed pleasing in your hearts, and ye conceived an evil thought, for ye are a people lost (in wickedness)."”
