Quran 29:10 Al-'Ankabut, ayah 10 of 69

وَمِنَ ٱلنَّاسِ مَن يَقُولُ ءَامَنَّا بِٱللَّهِ فَإِذَآ أُوذِىَ فِى ٱللَّهِ جَعَلَ فِتْنَةَ ٱلنَّاسِ كَعَذَابِ ٱللَّهِ وَلَئِن جَآءَ نَصْرٌ مِّن رَّبِّكَ لَيَقُولُنَّ إِنَّا كُنَّا مَعَكُمْ ۚ أَوَلَيْسَ ٱللَّهُ بِأَعْلَمَ بِمَا فِى صُدُورِ ٱلْعَـٰلَمِينَ ۝١٠

29:10 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?
