Qur'an 9:124

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

“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.”
