Al Mutawakkil and Aloeswood.

It is said that aloeswood was in such short supply in the time of the caliph Al Mutawakkil that he sent an envoy to India with presents to request a supply. The envoy who was apparently the famous courtier Ibn Hamdūn al-Nadīm, found the king of India in Lahuwār (Lahore?) to be most hospitable, for he had been raised in exile in Oman and was thus conversant with Arabic as well as Indian culture. His court was rich with imported goods from the Middle East and Iran, including perfumes.

“Before him were vessels of gold and silver; and many Iraqi metalworks, all beautiful and filled with camphor, rosewater, ambergris, the compound perfume called nadd and figurines. The nadd was likely an import from the Middle East rather than an Indian incense, given the context and the figurines would have been made from aromatics such as ambergris. At the end of lbn Hamdūn's extended stay the king, whose friend he had become, burned for him a rare aloeswood that was slightly smaller than half a dāniq. It had an indescribably pleasant scent, and it lingered in cloth after repeated washing with soap. Apparently, this rare scent was the stuff of legends, for the wood grew in an inaccessible place and only could be had by shooting deer that happened to have been there and sometimes were found chewing on bits of it, hence its extreme rarity. Al Mutawakkil received half of a ratl of it and deemed it worth the expedition after he had censed with it."
