They are the ones who denied Revelation and hindered you from the Sacred Mosque and the sacrificial animals, detained from reaching their place of sacrifice. Had there not been believing men and believing women whom ye did not know that ye were trampling down and on whose account a crime would have accrued to you without (your) knowledge, (Allah would have allowed you to force your way, but He held back your hands) that He may admit to His Mercy whom He will. If they had been apart, We should certainly have punished the Unbelievers among them with a grievous Punishment.
