On their way back to Madinah, at a large sand hill, the Prophet sallallaahu 'alayhi wa sallam divided the spoils equally among the fighters after he had taken Al-Khums (one-fifth). When they reached As-Safra', he ordered that two of the prisoners should be killed. They were An-Nadr bin Al-Harith and 'Uqbah bin Abi Muait, because they had persecuted the Muslims in Makkah, and harboured deep hatred towards Allaah and His Messenger sallallaahu 'alayhi wa sallam . In a nutshell, they were criminals of war in modern terminology, and their execution was an awesome lesson to oppressors. 'Uqbah forgot his pride and cried out, "Who will look after my children O Messenger of Allaah?" The Prophet sallallaahu 'alayhi wa sallam answered, "The Fire (of Hell)."

Abu Bakr suggested that he should ransom them, explaining this by saying: "They are after all our relatives, and this money would give us strength against the disbelievers, moreover, Allaah could guide them to Islaam." Umar advised killing them, saying, "They are the leaders of Kufr (disbelief)." The Prophet sallallaahu 'alayhi wa sallam preferred Abu Bakr's suggestion to that of Umar's. The following day, Umar called on the Prophet sallallaahu 'alayhi wa sallam and Abu Bakr to see them weeping. He showed extreme astonishment and inquired about the situation so that he might weep if it was worth weeping for, or else he would feign weeping.
