Believers! Fight against the unbelievers who live around you; and let them find in you sternness. Know that Allah is with the God-fearing. 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 in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers. 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 And whenever a surah is revealed, they glance at each other as though saying: "Is anyone watching?" Then they slip away. Allah has turned away their hearts for they are a people who are bereft of understanding. 127 There has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you and to the believers is kind and merciful. 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
