{ Say to those of the Bedouins who stayed behind: You will be called to a people of great might, you will fight them or they will yield; and if you obey, Allah will grant you a fine reward, but if you turn away as you turned away before, He will punish you painfully } Al-fath 16

{ You will fight them or they will yield } : that is, jihad against them and fighting them is prescribed for you, unceasingly, your continuous obligation; and you are to either gain victory over them or they yield [yuslimun, i.e. become Muslims] and enter into your religion without fighting but by choice. Then the Mighty and Sublime says: { And if you obey } : that is, if you respond, and mobilize for jihad, and carry out your duty concerning this.
