وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا بِٱللَّهِ فَإِذَآ أُوذِىَ فِى ٱللَّهِ جَعَلَ فِتْنَةَ ٱلنَّاسِ كَعَذَابِ ٱللَّهِ وَلَئِن جَآءَ نَصْرٌۭ مِّن رَّبِّكَ لَيَقُولُنَّ إِنَّا كُنَّا مَعَكُمْ ۚ أَوَلَيْسَ ٱللَّهُ بِأَعْلَمَ بِمَا فِى صُدُورِ ٱلْعَٰلَمِينَ
Of mankind is he who saith: We believe in Allah, but, if he be made to suffer for the sake of Allah, he mistaketh the persecution of mankind for Allah's punishment; and then, if victory cometh from thy Lord, will say: Lo! we were with you (all the while). Is not Allah Best Aware of what is in the bosoms of (His) creatures?
