سورة Al-Fath ( The Victory ) - الآية 25

It is they who disbelieved and prevented you from the Sacred Mosque and detained the sacrificial animals[14] from reaching their place of sacrifice. If it had not been for the believing men and women whom you could not identify, you might have trampled over them, thus incurring guilt unknowingly, [We would have let you march to Makkah]. [This was] so that Allah may admit to His mercy whom He wills[15]. If they had been distinct [from the disbelievers], We would surely have inflicted on those who disbelieved among them a painful punishment.
