‘Abdullāh ibn ‘Amr (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: ''The blood money of the semi-intentional killing is as aggravated as that of intentional killing, but the perpetrator is not to be killed. This happens when the devil stirs enmity between people, causing them to shed blood but not due to grudge or carrying weapons in fighting.''
This Hadīth shows that the blood money for the semi-intentional killing – which results from hitting with something that generally does not kill such as a stick – is as binding as the blood money for intentional killing. Its amount is one hundred camels; thirty of which should have completed four years of age and started the fifth, thirty should have completed three years of age and started the fourth, and forty should be pregnant she-camels. Mostly, semi-intentional killing is not caused by animosity or the carrying of weapons. Rather, the devil might whisper to people to attack each other because of joking or playing. So, they engage in fighting, leading to unintentional killing and thus blood is shed and payment of blood money becomes obligatory.
