Masri, the chairman of Amman-based Arab Bank, was detained last Tuesday hours before he was planning to leave after chairing meetings of companies he owns, sources said.
The Saudi authorities have not commented on his detention, which followed the biggest purge of the Saudi kingdom's rich and powerful in its modern history. His confidants had warned him not to travel to the Saudi capital after the mass arrests in early November, the sources said.
The detention sent shock-waves through business circles in Jordan and the Palestinian territories. Masri's multi-billion- dollar investments in hotels and banking in Jordan are a cornerstone of the economy of the kingdom and he is by far the biggest investor in Palestinian territories.
Masri said on Sunday that he would be returning to Jordan after finishing business meetings this week.
"All is well and am happy (to be released) and I was given all respect by everyone here," a Saudi citizen of Palestinian origin, told Reuters from his home in Riyadh.
He is the founder of Saudi Astra Group, which has wide interests in diversified industries ranging from agro-industry to telecommunications, construction and mining across the region.
