O you who believe! fight those of the unbelievers who are near to you and let them find in you hardness; and know that Allah is with those who guard (against evil). 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 chapter is sent down, they glance at each other, (asking): 'Does anyone see you' Then they turn away. Allah has turned away their hearts, for they are a nation who do not understand. 127 Indeed, there has come to you a Messenger from your own, he grieves for your suffering, and is anxious about you, and is gentle, merciful to the believers. 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
