That is because Allah would not change a favor which He had bestowed upon a people until they change what is within themselves. And indeed, Allah is Hearing and Knowing.
[Theirs is] like the custom of the people of Pharaoh and of those before them. They denied the signs of their Lord, so We destroyed them for their sins, and We drowned the people of Pharaoh. And all [of them] were wrongdoers.
Indeed, the worst of living creatures in the sight of Allah are those who have disbelieved, and they will not [ever] believe -
The ones with whom you made a treaty but then they break their pledge every time, and they do not fear Allah .
So if you, [O Muúammad], gain dominance over them in war, disperse by [means of] them those behind them that perhaps they will be reminded.
If you [have reason to] fear from a people betrayal, throw [their treaty] back to them, [putting you] on equal terms. Indeed, Allah does not like traitors.
And let not those who disbelieve think they will escape. Indeed, they will not cause failure [to Allah ].
And prepare against them whatever you are able of power and of steeds of war by which you may terrify the enemy of Allah and your enemy and others besides them whom you do not know [but] whom Allah knows. And whatever you spend in the cause of Allah will be fully repaid to you, and you will not be wronged.
And if they incline to peace, then incline to it [also] and rely upon Allah . Indeed, it is He who is the Hearing, the Knowing.
