وَإِذَا مَآ أُنزِلَتْ سُورَةٌ فَمِنْهُم مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَـٰذِهِۦٓ إِيمَـٰنًا ۚ فَأَمَّا ٱلَّذِينَ ءَامَنُوا۟ فَزَادَتْهُمْ إِيمَـٰنًا وَهُمْ يَسْتَبْشِرُونَ
“Whenever a surah 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.”
Part of the well-established hypocrites-who-stayed-behind-from-Tabuk passage of Surat al-Tawbah.
