﴿ وَذَٰلِكُمْ ظَنُّكُمُ ٱلَّذِى ظَنَنتُم بِرَبِّكُمْ أَرْدَىٰكُمْ فَأَصْبَحْتُم مِّنَ ٱلْخَٰسِرِينَ ﴾
“and that very thought which you thought about your Sustainer has brought you to perdition, and so now you find yourselves among the lost!””
(That, your thought which ye did think about your Lord) this which you said falsely about your Lord because of surmise (hath ruined you) has destroyed you; (and ye find yourselves (this day) among the lost) by being subject to punishment.
