وَاِذَا مَآ اُنْزِلَتْ سُوْرَةٌ فَمِنْهُمْ مَّنْ يَّقُوْلُ اَيُّكُمْ زَادَتْهُ هٰذِهٖٓ اِيْمَانًاۚ فَاَمَّا الَّذِيْنَ اٰمَنُوْا فَزَادَتْهُمْ اِيْمَانًا وَّهُمْ يَسْتَبْشِرُوْنَ ( التوبة: ١٢٤ )
Wa izaa maaa unzilat Sooratun faminhum mai yaqoolu aiyukum zaadat hu haazihee eemaanaa; fa ammal lazeena aamanoo fazaadat hum eemaananw wa hum yastabshiroon (at-Tawbah 9:124)
Sahih International:
And whenever a Surah 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. (At-Tawbah [9] : 124)
1 Mufti Taqi Usmani
When a Sūrah is sent down, some of them (the hypocrites) say, “Whose faith from among you has been increased by this?” So far as the believers are concerned, it has certainly increased their faith, and they are quite happy.
