O you who have believed, fight those adjacent to you of the disbelievers and let them find in you harshness. And know that Allah is with the righteous. 123 Whenever a chapter is sent down to you, some ask: 'Which of you has it increased in belief' It will surely increase the belief of the believers and they are joyful. 124 But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers. 125 See they not that they are tested once or twice in every year? Still they turn not in repentance, neither pay they 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 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
