(At-Thouba) 9 : 124
وَإِذَا مَا أُنْزِلَتْ سُورَةٌ فَمِنْهُمْ مَنْ يَقُولُ أَيُّكُمْ زَادَتْهُ هَٰذِهِ إِيمَانًا ۚ فَأَمَّا الَّذِينَ آمَنُوا فَزَادَتْهُمْ إِيمَانًا وَهُمْ يَسْتَبْشِرُونَ
And whenever a Surath is revealed, there are among them who ask: "Which of you has increased faith with this?" Then for those who believed, it will increase their faith and they are rejoicing with It.
