Is the death of a husband considered accidental killing if his wife accidentally gave him insecticide instead of cough medicine, and what are the consequences for the wife?

Scholars differed regarding one who unwittingly gave poison to another to drink, holding two views: 1. It is an accidental killing, necessitating blood money and expiation. 2. Nothing is required except disciplinary punishment, especially if the poisoned person drank the poison by choice, or if it was merely an act of offering the poison.

The Mufti believes that nothing is incumbent upon you in this case, but the more cautious approach is to offer expiation and pay blood money to the heirs of the deceased, unless they forgive.
