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 And whenever a new surah is revealed some of the hypocrites ask the believers (in jest): "Whose faith has increased because of this?" As for those who believe, it will certainly increase their faith, and they are joyful over that. 124 But to those whose hearts are sick, it adds more filth to their hearts and they die as disbelievers. 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 sent down they look on at each other as though saying: observeth you anyone? Thereafter they turn to go; Allah hath turned their hearts, for verily they are people who understand not. 127 Now there has come to you a Messenger from among yourselves; grievous to him is your suffering; anxious is he over you, gentle to the believers, compassionate. 128 But if those [who are bent on denying the truth] turn away, say: "God is enough for me! There is no deity save Him. In Him have I placed my trust, for He is the Sustainer, in awesome almightiness enthroned." 129
