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 As for those whose hearts are diseased, they will be increased in filth added to their filth, so that they die as unbelievers. 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 sura is sent down, they look one at another: 'Does anyone see you?' Then they turn away. God has turned away their hearts, for that they are a people who do not understand. 127 INDEED, there has come unto you [O mankind] an Apostle from among yourselves: heavily weighs - upon him [the thought] that you might suffer [in the life to come]; full of concern for you [is he, and] full of compassion and mercy towards the believers. 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
