This is no big deal to me, but what you posted is not entirely accurate.
In the Koran it says in 623. * If a person dies on a ship and if there is no fear of the decay of the dead body and if there is no problem in retaining it for sometime on the ship, it should be kept on it and buried in the ground after reaching the land. Otherwise, after giving Ghusl, Hunut, Kafan and Namaz-e-Mayyit it should be lowered into the sea in a vessel of clay or with a weight tied to its feet. And as far as possible it should not be lowered at a point where it is eaten up immediately by the sea predators.
If he died yesterday, what difference would 48 hours make? Plus there'd be undoubtable proof that the man is actually Osama and that he's actually dead. Can you say DNA evidence? Just my opinion though.
News reports have made claims before that Obama was killed, only for him to rise back from the grave.
