And it is not for the believers to go forth [to battle] all at once. For there should separate from every division of them a group [remaining] to obtain understanding in the religion and warn [i.e., advise] their people when they return to them that they might be cautious.
O you who have believed, fight against those adjacent to you of the disbelievers and let them find in you harshness. And know that Allāh is with the righteous.
And whenever a sūrah is revealed, there are among them [i.e., the hypocrites] those who say, "Which of you has this increased in faith?" As for those who believed, it has increased them in faith, while they are rejoicing.
But as for those in whose hearts is disease, it has [only] increased them in evil [in addition] to their evil.1 And they will have died while they are disbelievers.
And whenever a sūrah is revealed, they look at each other, [as if saying], "Does anyone see you?" and then they dismiss themselves. Allāh has dismissed their hearts because they are a people who do not understand.
There has certainly come to you a Messenger from among yourselves. Grievous to him is what you suffer; [he is] concerned over you [i.e., your guidance] and to the believers is kind and merciful.
