Narrated 'Amr bin Murrah: that Abu 'Ubaidah bin 'Abdullah narrated from 'Abdullah bin Mas'ud who said: "On the Day of Badr, when the captives were brought, the Messenger of Allah (ﷺ) said 'What do you say about these captives?' So he mentioned the story. And the Messenger of Allah (ﷺ) said 'Not one of them should be released without a ransom, or a blow to the neck.'" So 'Abdullah bin Mas'ud said: "O Messenger of Allah! With the exception of Suhail bin Baidam for indeed I heard him mentioning Islam." He said: "So the Messenger of Allah (ﷺ) was silent." He said: "I have not seen a day upon which I was more fearful of stones falling from the heavens upon my head that the day." [He said:] "Until the Messenger of Allah (ﷺ) said: 'Except for Suhail bin Al-Baida.'" He said: "And the Qur'an was revealed in accordance with the view of 'Umar. 'It is not (fitting) for a Prophet that he should have prisoners of war until he has fought (his enemies thoroughly) in the land...' until the end of the Ayat."
