Does administering glucose to a sick person who subsequently died constitute accidental killing?

If it is proven that the death was due to a mistake in administering the dosage, then this is considered accidental killing, and the blood money (diyah) is obligatory upon the 'aqilah (male relatives on the father's side) of the one who administered the dosage, and expiation (kaffarah) is also obligatory upon him. The one who directly administered the dosage is responsible, not the one who merely indicated it. However, in cases of doubt and unproven causation of death, the fundamental principle is the presumption of innocence, and neither blood money nor expiation is obligatory.
