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 Surah is sent down, there are some of them who say which of you hath this increased in faith! As for those who believe, it hath increased them in faith, and they rejoice. 124 But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers. 125 Do they not see that they are tried every year once or twice? Yet still they do not repent, nor do they remember. 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 Certainly an Apostle has come to you from among yourselves; grievous to him is your falling into distress, excessively solicitous respecting you; to the believers (he is) 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
