d. Imam Hanbali : A person is found to be missing in an situation, where the situation was destroyed, like those lost in the war, sailing or in the plane that crashed, then it should be investigated for 4 years and if one is lost in a condition that is not the case of destruction, like those who go to trade or travel, or study and so it is in this state there are 2 opinions :
i) Wait until the 90 years since it was born
ii) Handed to Ijtihad of judge ( Judge Decision )
