Al-Anfal 8:71

Wa-in yureedoo khiyanataka faqad khanooAllaha min qablu faamkana minhum wallahuAAaleemun hakeem

But if they intend to betray you - then they have already betrayed Allāh before, and He empowered [you] over them. And Allāh is Knowing and Wise.

And if they intend to commit treachery against you, then, they have already committed treachery against Allah, and in turn Allah has given you full control over them. And Allah is All-Knowing, Wise.
