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 Whenever a chapter is sent down, there are some of them who say, "Which of you has had his faith increased by it?" But, as for those who believe, it increases their faith and they rejoice, 124 But it adds disbelief to disbelief for those whose hearts are filled with doubt, and they die disbelieving. 125 See they not that they are tried once or twice every year (with different kinds of calamities, disease, famine, etc.)? Yet, they turn not in repentance, nor do they learn a lesson (from it). 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 has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you and to the believers is kind and merciful. 128 But if they turn away, say, "God suffices me: there is no deity but He: in Him I have put my trust. He is the Lord of the Glorious Throne." 129
