Surah At-Tawbah, Verse 124

وَإِذَا مَآ أُنزِلَتۡ سُورَةٞ فَمِنۡهُم مَّن يَقُولُ أَيُّكُمۡ زَادَتۡهُ هَٰذِهِۦٓ إِيمَٰنٗاۚ فَأَمَّا ٱلَّذِينَ ءَامَنُواْ فَزَادَتۡهُمۡ إِيمَٰنٗا وَهُمۡ يَسۡتَبۡشِرُونَ١٢٤

wa-idhā mā unzilat sūratun famin'hum man yaqūlu ayyukum zādathu hādhihi īmānan fa-ammā alladhīna āmanū fazādathum īmānan wahum yastabshirūna

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.
