What is the Islamic legal ruling and the type of killing (intentional or accidental) that applies to a driver who ran over three people, two of whom died and the third was injured, knowing that the driver was drunk, driving recklessly and at excessive speed on the sidewalk in a residential area?

A driver who drives while intoxicated and causes accidents is committing acts forbidden by Islamic law that warrant punishment. Drinking alcohol is a grave sin, and driving while intoxicated endangers people's lives. An accident that does not involve intent to kill entails the same consequences as accidental killing: expiation (which is freeing a believing slave, or, if one is not found, fasting for two consecutive months) and blood money (Diyya) paid to the victim's family by the perpetrator's 'Aqila (male relatives on the paternal side).
