Al-Fath 48:25

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.

[14] i.e., The Prophet (ﷺ) had brought along with him seventy camels to be sacrificed after completing the rituals of ‘Umrah (the minor pilgrimage).
[15] Thus, not only the Muslims in Makkah who were not known to their fellow believers were safe, but also those pagans who later embraced Islam were safe too.

They are the ones who disbelieved and obstructed you from al-Masjid al-Ḥarām while the offering[1516] was prevented from reaching its place of sacrifice. And if not for believing men and believing women whom you did not know - that you might trample [i.e., kill] them and there would befall you because of them dishonor without [your] knowledge - [you would have been permitted to enter Makkah]. [This was so] that Allāh might admit to His mercy whom He willed. If they had been apart [from them], We would have punished those who disbelieved among them with painful punishment

[1516] i.e., seventy camels intended for sacrifice and feeding of the poor.

25. They are the ones who disbelieved (in the Oneness of Allâh - Islâmic Monotheism) and hindered you from Al-Masjid-al-Harâm (at Makkah) and detained the sacrificial animals from reaching their place of sacrifice. Had there not been believing men and believing women whom you did not know, that you may kill them and on whose account a sin would have been committed by you without (your) knowledge, that Allâh might bring into His Mercy whom He wills - if they (the believers and the disbelievers) had been apart, We verily would have punished those of them who disbelieved with painful torment.

These it was who disbelieved and debarred you from the Inviolable Place of Worship, and debarred the offering from reaching its goal. And if it had not been for believing men and believing women, whom ye know not - lest ye should tread them under foot and thus incur guilt for them unknowingly; that Allah might bring into His mercy whom He will - If (the believers and the disbelievers) had been clearly separated We verily had punished those of them who disbelieved with painful punishment.
