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 there cometh down a sura, some of them say: "Which of you has had His faith increased by it?" Yea, those who believe,- their faith is increased and they do rejoice. 124 And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers. 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 there comes down a Surah (chapter from the Quran), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not. 127 There has come to you a Messenger of Allah from among yourselves, who is distressed by the losses you sustain, who is ardently desirous of your welfare and is tender and merciful to those that believe. 128 But if they turn away, say (O Muhammad SAW): "Allah is sufficient for me. La ilaha illa Huwa (none has the right to be worshipped but He), in Him I put my trust and He is the Lord of the Mighty Throne. 129
