Musnad Ahmad 28:242

Abu al-Nadr and Abd al-Samad narrated to us, they said: Muhammad narrated to us, Sulayman narrated to us, from Amr ibn Shu’ayb, from his father, from his grandfather, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The blood money for quasi-intentional homicide is aggravated, like the blood money for intentional homicide, but its perpetrator is not to be killed; and that is because Satan incites [strife] between people." Abu al-Nadr said: "It is when there is shooting blindly, without there being a trial or the carrying of weapons."
