(Fuswilath) 41 : 23
وَذَٰلِكُمْ ظَنُّكُمُ الَّذِي ظَنَنْتُمْ بِرَبِّكُمْ أَرْدَاكُمْ فَأَصْبَحْتُمْ مِنَ الْخَاسِرِينَ
And that was your guessing you guessed about your Lord which led you into perdition, thus you were becoming among the losers.
For the Arabic Quran reading Fujjar, who live by considering the ways of their forefathers and the books of deeds written by the hypocrites as a criterion, it will be clear that their guessing about Allah was the worst and wrong. See explanation 17: 13-15; 39: 67; 48: 6, 12.
