The funeral for Saudi Arabia's King Abdullah is set to be a simple affair, NBC News reported. His net worth is believed to be $20 billion, but he will be laid to rest in an unmarked grave, according to tradition. Abdullah will first be bathed according to Islamic ritual, then wrapped in two pieces of plain white cloth. His body will be taken to the Imam Turki Bin Abdullah Grand Mosque in Riyadh for a ceremony that is open to the public. Tens of thousands, including Vice President Joe Biden, are expected to pay their condolences during a three-day period of mourning.
