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 When a chapter (of the Quran) is revealed, some people ask others, "Whose faith among you people has received strength from this (revelation)?" It (the revelation) certainly strengthens the faith of the believers and they consider it to be a glad news. 124 But as for those in whose hearts is disease, each new message but adds another [element of] disbelief to the disbelief which they already harbour, and they die while [still] refusing to acknowledge the truth. 125 Do they not see that they are tried every year once or twice but then they do not repent nor do they remember? 126 And whenever a chapter is revealed, they cast glances at one another: Does any one see you? Then they turn away: Allah has turned away their hearts because they are a people who do not understand. 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 So, if they turn away, say to them: "God is sufficient for me. There is no God but He; I depend on Him alone, the Lord of the glorious Throne." 129
