وَإِذَا مَآ أُنزِلَتْ سُورَةٌ فَمِنْهُم مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَـٰذِهِۦٓ إِيمَـٰنًا ۚ فَأَمَّا ٱلَّذِينَ ءَامَنُوا فَزَادَتْهُمْ إِيمَـٰنًا وَهُمْ يَسْتَبْشِرُونَ

Wa-itha ma onzilat sooratunfaminhum man yaqoolu ayyukum zadat-hu hathihi eemananfaamma allatheena amanoo fazadat-humeemanan wahum yastabshiroon

And whenever a sūrah is revealed, there are among them [i.e., the hypocrites] those who say, "Which of you has this increased in faith?" As for those who believed, it has increased them in faith, while they are rejoicing.
