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 And whenever a surah is revealed there are some of them who say: Which one of you hath thus increased in faith? As for those who believe, it hath increased them in faith and they rejoice (therefor). 124 But to those whose hearts are sick, it adds more filth to their hearts and they die as disbelievers. 125 Are they, then, not aware that they are being tested year-in, year-out? And yet, they do not repent and do not bethink themselves [of God]; 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 To you has come an Apostle from among you. Any sorrow that befalls you weighs upon him; He is eager for your happiness, full of concern for the faithful, compassionate and kind. 128 Therefore, if they turn away, say: 'Allah is sufficient for me. There is no god except He. In Him I have put my trust. He is the Lord of the Mighty Throne' 129
