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 sura is sent down to thee, some of them say, 'Which of you has this increased in belief?' As for the believers, them it has increased in belief, and they are joyful. 124 But those in whose hearts is a disease,- it will add doubt to their doubt, and they will die in a state of Unbelief. 125 Do they not see that they are tried every year once or twice? Yet they neither repent nor take heed. 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 Indeed, there has come to you a Messenger from your own, he grieves for your suffering, and is anxious about you, and is gentle, merciful to the believers. 128 Now, if they turn away (O Muhammad) say: Allah sufficeth me. There is no Allah save Him. In Him have I put my trust, and He is Lord of the Tremendous Throne. 129
