Is the full diyah obligatory in an accident that resulted in death, where the fault was shared by both parties? And is the diyah to be estimated by the value of silver at the time of the accident or by its current value, and what is its amount? And is it obligatory to fast for two consecutive months as expiation, and what is the ruling on breaking the fast for one day during them due to an excuse?

If the error is shared between the driver and the deceased in a traffic accident, then the diyya (blood money) is determined by the proportion of the error, and it is borne by the 'aqila (the male agnatic relatives of the offender). The original diyya is one hundred camels, or twelve thousand silver dirhams (35.700 kilograms). If its value is paid in paper currency, then the value considered is that on the day of payment or the day of the court's ruling. As for the expiation for unintentional killing, which is fasting for two consecutive months, it is obligatory regardless of the proportion of the error. Illness does not interrupt the continuity, unlike breaking the fast without a valid excuse.
