Evidence:
He it is Who sent down As Sakinah (tranquillity) into the hearts of the believers, that they may grow more in Emaan along with their (present) Emaan. (Quran 48:4)
And whenever a Surah is revealed some of them say, ‘Which of you has had his Emaan increased by it?’ As for those who believe, it has increased their Emaan and they rejoice (Quran 9: 124)
Anas narrated that the Prophet said, ‘Whoever said La Ilaaha Illallaah and has in his heart Khair (good) equal to the weight of an atom will be taken out of Hell.’ The Prophet said. ‘Min Emaan makaana Khair,’ defining Khair to mean Emaan in this hadeeth. (saheeh of bukhaari)
