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 YET WHENEVER a surah [of this divine writ] is bestowed from on high, some of the deniers of the truth are prone to ask, "Which of you has this [message] strengthened in his faith?" Now as for those who have attained to faith, it does strengthen them in their faith, and they rejoice in the glad tiding [which God has given them]. 124 But as for those in whose hearts is disease, it has [only] increased them in evil [in addition] to their evil. And they will have died while they are disbelievers. 125 Do they not realize that God tests them once or twice a year but, nevertheless, they do not repent and give it proper thought? 126 and whenever a surah is bestowed from on high, they look at one another [and say, as it were,] "Is there anyone who can see what is in your hearts?" - and then they turn away. God has turned their hearts away [from the truth] - for they are people who will not grasp it. 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 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
