وَإِذا ما أُنزِلَت سورَةٌ فَمِنهُم مَن يَقولُ أَيُّكُم زادَتهُ هـٰذِهِ إيمانًا ۚ فَأَمَّا الَّذينَ آمَنوا فَزادَتهُم إيمانًا وَهُم يَستَبشِرونَ

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.
