Surah Al-Ankaboot, Verse 10
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
Translation — Sahih International
And of the people are some who say, "We believe in Allah," but when one [of them] is harmed for [the cause of] Allah, they consider the trial of the people as [if it were] the punishment of Allah. But if victory comes from your Lord, they say, "Indeed, We were with you." Is not Allah most knowing of what is within the breasts of all creatures?
