O you who believe! fight those of the unbelievers who are near to you and let them find in you hardness; and know that Allah is with those who guard (against evil). 123 And whenever a surah is revealed there are some of them who say: Which one of you hath thus increased in faith? As for those who believe, it hath increased them in faith and they rejoice (therefor). 124 And as for those in whose hearts is a disease, unto them it hath increased pollution to their pollution, and they die while they are infidels. 125 Do they not see that they are tried every year once or twice? Yet they do not repent, nor would they be admonished. 126 And whenever a chapter is sent down, one of them looks at the other; “Is there someone watching you?” – and then they turn away; Allah has inverted their hearts because they are a people who do not understand. 127 There hath come unto you a messenger, (one) of yourselves, unto whom aught that ye are overburdened is grievous, full of concern for you, for the believers full of pity, merciful. 128 But if they turn back, say: Allah is sufficient for me, there is no god but He; on Him do I rely, and He is the Lord of mighty power. 129
