O you who have believed, fight those adjacent to you of the disbelievers and let them find in you harshness. And know that Allah is with the righteous. 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 a disease (of doubt, disbelief and hypocrisy), it will add suspicion and doubt to their suspicion, disbelief and doubt, and they die while they are disbelievers. 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 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
