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 it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 125 Do they not see that they are tried once or twice in every year, yet they do not turn (to Allah) nor do they mind. 126 And whenever a chapter is sent down, one of them looks at the other; “Is there someone watching you?” – and then they turn away; Allah has inverted their hearts because they are a people who do not understand. 127 Now there has come to you a Messenger from among yourselves; grievous to him is your suffering; anxious is he over you, gentle to the believers, compassionate. 128 So if they turn their backs, say: 'God is enough for me. There is no god but He. In Him I have put my trust. He is the Lord of the Mighty Throne.' 129
