They were ungrateful, and they barred you from the Masjid al-Haram, and were ones who detained the sacrificial gift from reaching its place of sacrifice. If it had not been for men, ones who believe, and for women, ones who believe, whom you know not that you tread on them and guilt should light on you without your knowledge. This was so that God may cause to enter into His mercy whomever He wills. If they were clearly apart, separated, We would have punished those who were ungrateful among them with a painful punishment.
