Surah At-Taubah (The Repentance), Verse 124

وَاِذَا مَاۤ اُنْزِلَتْ سُوْرَةٌ فَمِنْهُمْ مَّنْ یَّقُوْلُ اَیُّكُمْ زَادَتْهُ هٰذِهٖۤ اِیْمَانًا فَاَمَّا الَّذِیْنَ اٰمَنُوْا فَزَادَتْهُمْ اِیْمَانًا وَّهُمْ یَسْتَبْشِرُوْنَ ۟

Wa izaa maaa unzilat Sooratun faminhum mai yaqoolu aiyukum zaadat hu haazihee eemaanaa; fa ammal lazeena aamanoo fazaadat hum eemaananw wa hum yastabshiroon

“Whenever there cometh down a sura, some of them say: "Which of you has had His faith increased by it?" Yea, those who believe,- their faith is increased and they do rejoice.”
