At-Tawbah 9:124

Wa-itha ma onzilat sooratunfaminhum man yaqoolu ayyukum zadat-hu hathihi eemananfaamma allatheena amanoo fazadat-humeemanan wahum yastabshiroon

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.

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.
