Is the mother responsible for the death of her son who fell from the fourth floor, despite their prior knowledge of his medical condition (epilepsy) and hyperactivity?

We advise you to be patient and content with Allah's decree and destiny. Know that Allah has promised paradise and the House of Praise to the one who is patient upon the loss of their child. If there was no negligence or shortcoming on your part concerning your son, then there is nothing upon you.
