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 When a Surah is revealed some of them remark: "Whose faith among you has it increased?" It does increase the faith of those who believe, and they rejoice. 124 but as for those with sickness in their hearts, it adds defilement to their defilement and they die in a state of denial of truth. 125 Do they not see that they are tried once or twice in every year, yet they do not turn (to Allah) nor do they mind. 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 they turn away, [O Muhammad], say, "Sufficient for me is Allah; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne." 129
