O you who have believed, fight those adjacent to you of the disbelievers and let them find in you harshness. And know that Allah is with the righteous. 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 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 Behold they not that they are tried every year once or twice? Yet they repent not, nor are they admonished. 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 To you has come an Apostle from among you. Any sorrow that befalls you weighs upon him; He is eager for your happiness, full of concern for the faithful, compassionate and kind. 128 But if they turn back, say: Allah is sufficient for me, there is no god but He; on Him do I rely, and He is the Lord of mighty power. 129
