9:124
وَإِذَا مَآ أُنزِلَتْ سُورَةٌ فَمِنْهُم مَّن يَقُولُ أَيُّكُمْ زَادَتْهُ هَـٰذِهِۦٓ إِيمَـٰنًا ۚ فَأَمَّا ٱلَّذِينَ ءَامَنُوا۟ فَزَادَتْهُمْ إِيمَـٰنًا وَهُمْ يَسْتَبْشِرُونَ
9:124
And whenever a new surah is revealed some of the hypocrites ask the believers (in jest): "Whose faith has increased because of this?" As for those who believe, it will certainly increase their faith, and they are joyful over that. - Abul Ala Maududi (English)
