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 As for those whose hearts are diseased, they will be increased in filth added to their filth, so that they die as unbelievers. 125 See they not that they are tried every year once or twice? Yet they turn not in repentance, and they take no heed. 126 Whenever a chapter is revealed, they glance at each other, asking, "Is anyone watching?" Then they turn away. God has turned their hearts away, because they are people who do not understand. 127 There has come to you a Messenger of your own. Your suffering distresses him: he is deeply concerned for your welfare and full of kindness and mercy towards the believers. 128 If, then, they turn away, say thou: sufficing unto me is Allah, there is no god but he, on Him I rely and He is the Lord of Mighty Throne. 129
