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 there cometh down a sura, some of them say: "Which of you has had His faith increased by it?" Yea, those who believe,- their faith is increased and they do 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 Do they not know that they are tried every year once or twice? Even then they do not repent and take heed. 126 And whenever a surah is revealed, they glance at each other as though saying: "Is anyone watching?" Then they slip away. Allah has turned away their hearts for they are a people who are bereft of understanding. 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 Now, if they turn away (O Muhammad) say: Allah sufficeth me. There is no Allah save Him. In Him have I put my trust, and He is Lord of the Tremendous Throne. 129
