Believers, fight the unbelievers near you for the cause of God so that they realize your strength and know that God is with the pious ones. 123 And whenever a Surah is sent down, there are some of them who say which of you hath this increased in faith! As for those who believe, it hath increased them in faith, and they rejoice. 124 but as for those with sickness in their hearts, it adds defilement to their defilement and they die in a state of denial of truth. 125 Do they not see that they are tried every year once or twice? Yet still they do not repent, nor do they remember. 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 Noble Messenger from among you – your falling into hardship aggrieves him, most concerned for your well being, for the Muslims most compassionate, most merciful. 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
