[Nisa 4:80] Whoever obeys the Noble Messenger has indeed obeyed Allah; and for those who turn away - We have not sent you as their saviour.
[Nisa 4:81] And they say, "We have obeyed"; and when they go away from you, a group of them spend the night conspiring against what they had said; and Allah records what they conspired by night; therefore O dear Prophet (Mohammed - peace and blessings be upon him) avoid them and rely upon Allah; and Allah is Sufficient as a Trustee (of affairs).
[Nisa 4:82] So do they not ponder about the Qur’an? And had it been from anyone besides Allah, they would certainly find much contradiction in it.
[Nisa 4:83] And when any news of safety or fear comes to them, they speak of it publicly; and had they referred it to the Noble Messenger and to those among them having authority, those among them who are able to infer would certainly learn the truth of the matter from them; and were it not for Allah’s munificence upon you, and His mercy, all of you would have certainly followed Satan - except a few.
[Nisa 4:84] Therefore O dear Prophet, fight in Allah's cause; you will not be burdened except for yourself, and urge the believers (to fight); it is likely that Allah will curb the strength of the disbelievers; and Allah's strike is most stinging and His punishment the most severe.
[Nisa 4:85] Whoever makes a noble intercession will have a share of it, and whoever makes an evil intercession will have a share of it; and Allah is Able to do all things.
[Nisa 4:86] And when you are greeted with some words, greet back with words better than it or with the same; indeed Allah will take account of everything.
