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 And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers. 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 there cometh down a Sura, they look at each other, (saying), "Doth anyone see you?" Then they turn aside: Allah hath turned their hearts (from the light); for they are a people that understand not. 127 INDEED, there has come unto you [O mankind] an Apostle from among yourselves: heavily weighs - upon him [the thought] that you might suffer [in the life to come]; full of concern for you [is he, and] full of compassion and mercy towards the believers. 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
