O Ye who believe! fight the infidels who are near unto you, and surely let them find in you sternness, and know that Allah is with the God-fearing, 123 When a chapter (of the Quran) is revealed, some people ask others, "Whose faith among you people has received strength from this (revelation)?" It (the revelation) certainly strengthens the faith of the believers and they consider it to be a glad news. 124 But to those whose hearts are sick, it adds more filth to their hearts and they die as disbelievers. 125 Do they not see that they are tried every year once or twice but then they do not repent nor do they remember? 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 Assuredly there hath come unto you an apostle from amongst yourselves: heavy upon him is that which harasseth you, solicitous for you, and with the believers tender and 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
