It was they who were bent on denying the truth, and who debarred you from the Sacred Mosque and who prevented your offering from reaching its place of sacrifice. And had it not been for the believing men and believing women [in Makkah] whom you might unwittingly have trampled underfoot, and on whose account you might have, unknowingly, become guilty, [God would have commanded you to fight it out with them; but He ordained it thus] so that He may bring whoever He will into His mercy. If they [the believers] had been clearly separated, We would have punished those who were bent on denying the truth with a painful punishment.
