What is [the matter] with you [that you are] two groups concerning the hypocrites,1 while Allāh has made them fall back [into error and disbelief] for what they earned.2 Do you wish to guide those whom Allāh has sent astray? And he whom Allāh sends astray - never will you find for him a way [of guidance].3
Translation: Saheeh International (English)
1 i.e., divided between two viewpoints - whether or not they should be fought and killed.
2 As the result of their disobedience and disloyalty.
3 Allāh (subḥānahu wa taʿālā) leaves or sends astray those who choose to reject His guidance.
Why is it, O believers, that you have become two groups differing over how to deal with the hypocrites? One group wants to fight against them because of their disbelief and another group wants to leave them because of their faith. You should not disagree over them for Allah has returned them to disbelief and misguidance because of their actions. Do you wish to guide those whom Allah has not shown the truth? If Allah misguides anyone, you will never find a way to guide such a person.
