O ye who believe! fight the unbelievers who gird you about, and let them find firmness in you: and know that Allah is with those who fear Him. 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 observe that they are tested once or twice every year? Yet they do not repent, nor do they heed advice! 126 Whenever a Surah is revealed they look at each other (so as to ask): "Is anyone looking at Us?" and then turn away. Indeed God has turned their hearts away (from the truth), for they cannot discern the law of heaven. 127 Now hath come unto you a Messenger from amongst yourselves: it grieves him that ye should perish: ardently anxious is he over you: to the Believers is he most kind and merciful. 128 Therefore, if they turn away, say: 'Allah is sufficient for me. There is no god except He. In Him I have put my trust. He is the Lord of the Mighty Throne' 129
