Here it says > Have you ever wondered why the Children of Ishmael were free, and mighty, while the Children of Israel were still enslaved to the Pharaoh? Among the descendants of Ishmael, the Ark was eventually inherited by the Prophet Shuaib (Jethro), whose daughter Safura (Zipporah), a princess, married Moses, prince of Egypt … Moses served Jethro the Ishmaelite Prophet and king for a number of years, learnt from him, and was given guardianship of the Ark of the Covenant by him, and the staff of Adam from it, to go and set the Children of Israel free. Through the blessings of the Ark, the Children of Israel became free, and the Pharaoh was destroyed. > >The Ark stayed in the family of Moses with the Children of Israel from this stage in history on wards and they placed in it the relics of Moses and Aaron as well. Moses and his brother and their family remained the chiefs of the Israelites and eventually placed it back in Bait ul-Maqdis … ~ Hidden Islamic History of the Ark of the Covenant But it doesn't mention a source describing Shuaib's possession of the Ark specifically. Are there Hadiths, tafsirs, or other classical sources which mention Shuaib (A"S) having the Tabut-as-Sakinah? And then which Ark is described? Was it used and moved with the other arks which were manufactured? Exactly where is it now!?
