O you who have attained to faith! Fight against those deniers of the truth who are near you, and let them find you adamant; and know that God is with those who are conscious of Him. 123 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. 124 And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers. 125 Do they not observe that they are tested once or twice every year? Yet they do not repent, nor do they heed advice! 126 And whenever there comes down a Surah (chapter from the Quran), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not. 127 Indeed, there has come to you a Messenger from your own, he grieves for your suffering, and is anxious about you, and is gentle, merciful to the believers. 128 But if they turn away, Say: "Allah sufficeth me: there is no god but He: On Him is my trust,- He the Lord of the Throne (of Glory) Supreme!" 129
