Surah 47. Muhammad, Ayah 22

The above interpolations are in tune with the explanation of this passage advanced by almost all of the classical commentators, who regard this rhetorical "question" as an allusion to the chaotic conditions of pre-Islamic Arabia, its senseless internecine wars, and the moral darkness from which Islam had freed its followers. Nevertheless, this verse has, like the whole of the passage of which it forms a part, a timeless import as well.

 As you did before Islam.

It is no use to say, as the Quraish said, that it is not seemly to fight against kith and kin. From one point of view the stand against sin brings "not peace, but a sword". It is a case of either subduing evil or being subdued by evil. If evil gets the upper hand, it is not likely to respect ties of kith and kin. It did not in the case of the holy Prophet and his adherents, and had to be suppressed, to bring about the conditions necessary for peace.
