Is someone who dies from a stroke due to anger considered a suicide?

Anger is the sum of all evil and a provocation from Satan. It has been forbidden except when for the sake of Allah. However, this prohibition refers to avoiding its causes and not acting upon what anger calls for, because anger itself is a natural emotion that cannot be repelled. Therefore, not everyone who dies while angry is considered a suicide or a murderer of himself, for anger is not a cause of suicide. And whoever commits a cause of suicide unintentionally is not considered a suicide.
