They were the ones who disbelieved, and who debarred you from the Sacred Mosque and prevented your offering from reaching its place of sacrifice. Had it not been for the fact that there were among them believing men and women unknown to you and whom you might have unwittingly trampled underfoot, and on whose account you would have unwittingly incurred guilt… God will admit to His grace whomever He wills. Had they stood apart, We would have inflicted on the unbelievers among them truly painful suffering.
