At Tawbah Ayah 124
وَإِذَا مَآ أُنزِلَتْ سُورَةٌ فَمِنْهُم مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَـٰذِهِۦٓ إِيمَـٰنًاۚ فَأَمَّا ٱلَّذِينَ ءَامَنُواْ فَزَادَتْهُمْ إِيمَـٰنًا وَهُمْ يَسْتَبْشِرُونَ ١٢٤
Whenever a sûrah is revealed, some of them ask ?mockingly?, “Which of you has this increased in faith?” As for the believers, it has increased them in faith and they rejoice.
