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

Whenever a chapter is revealed, some of them ask, “Which of you has this increased in faith?” As for those who have believed, it increases their faith and they are rejoicing.
