And whenever a surah is revealed, there are among the hypocrites those who say, "Which of you has this increased faith?" As for those who believed, it has increased them in faith, while they are rejoicing.
And whenever a surah is revealed, they look at each other, [saying], "Does anyone see you?" and then they dismiss themselves. Allah has dismissed their hearts because they are a people who do not understand.
