The Mutual Disillusion
يَعْلَمُ مَا فِى ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ وَيَعْلَمُ مَا تُسِرُّونَ وَمَا تُعْلِنُونَ ۚ وَٱللَّهُ عَلِيمٌۢ بِذَاتِ ٱلصُّدُورِ
He knows what is within the heavens and earth and knows what you conceal and what you declare. And Allah is Knowing of that within the breasts.

هُوَ ٱلَّذِى خَلَقَكُمْ فَمِنكُمْ كَافِرٌ وَمِنكُم مُّؤْمِنٌ ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ بَصِيرٌ
It is He who created you, and among you is the disbeliever, and among you is the believer. And Allah, of what you do, is Seeing.
خَلَقَ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضَ بِٱلْحَقِّ وَصَوَّرَكُمْ فَأَحْسَنَ صُوَرَكُمْ ۖ وَإِلَيْهِ ٱلْمَصِيرُ
He created the heavens and earth in truth and formed you and perfected your forms; and to Him is the [final] destination.
أَلَمْ يَأْتِكُمْ نَبَؤُا۟ ٱلَّذِينَ كَفَرُوا۟ مِن قَبْلُ فَذَاقُوا۟ وَبَالَ أَمْرِهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ
Has there not come to you the news of those who disbelieved before? So they tasted the bad consequence of their affair, and they will have a painful punishment.
ذَٰلِكَ بِأَنَّهُۥ كَانَت تَّأْتِيهِمْ رُسُلُهُم بِٱلْبَيِّنَـٰتِ فَقَالُوٓا۟ أَبَشَرٌ يَهْدُونَنَا فَكَفَرُوا۟ وَتَوَلَّوا۟ ۚ وَّٱسْتَغْنَى ٱللَّهُ ۚ وَٱللَّهُ غَنِىٌّ حَمِيدٌ
That is because their messengers used to come to them with clear evidences, but they said, "Shall human beings guide us?" and disbelieved and turned away. And Allah dispensed [with them]; and Allah is Free of need and Praiseworthy.
