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 Whenever a chapter is sent down, there are some of them who say, "Which of you has had his faith increased by it?" But, as for those who believe, it increases their faith and they rejoice, 124 And as for those in whose hearts is a disease, unto them it hath increased pollution to their pollution, and they die while they are infidels. 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 a Surah is sent down they look on at each other as though saying: observeth you anyone? Thereafter they turn to go; Allah hath turned their hearts, for verily they are people who understand not. 127 There hath come unto you a messenger, (one) of yourselves, unto whom aught that ye are overburdened is grievous, full of concern for you, for the believers full of pity, merciful. 128 But if they turn away, say, "God suffices me: there is no deity but He: in Him I have put my trust. He is the Lord of the Glorious Throne." 129
