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 YET WHENEVER a surah [of this divine writ] is bestowed from on high, some of the deniers of the truth are prone to ask, "Which of you has this [message] strengthened in his faith?" Now as for those who have attained to faith, it does strengthen them in their faith, and they rejoice in the glad tiding [which God has given them]. 124 And as for those in whose hearts is a disease, unto them it hath increased pollution to their pollution, and they die while they are infidels. 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 a surah is revealed, they glance at each other as though saying: "Is anyone watching?" Then they slip away. Allah has turned away their hearts for they are a people who are bereft of understanding. 127 There hath come unto you a messenger, (one) of yourselves, unto whom aught that ye are overburdened is grievous, full of concern for you, for the believers full of pity, merciful. 128 But if they turn away, Say: "Allah sufficeth me: there is no god but He: On Him is my trust,- He the Lord of the Throne (of Glory) Supreme!" 129
