I saw the cup of the Prophet ﷺ in the possession of Anas bin Malik. It had cracked, so he had it bound together with a silver wire. He said, "It is a fine, wide cup made of nudar wood."Anas said, "I gave the Messenger of Allah ﷺ drink from this cup more times than I can count."Ibn Sirin said that the cup had an iron ring on it, and Anas wanted to replace it with a ring of gold or silver, but Abu Talha said to him, "Do not alter anything that the Messenger of Allah ﷺ made," so he left it as it was.
رأيت قدح النبي ﷺ عند أنس بن مالك، وكان قد انصدع، فسلسله بفضة قال: هو قدح جيد عريض من نضار. قال: قال أنس: لقد سقيت رسول الله ﷺ في هذا القدح أكثر من كذا وكذا. قال: وقال ابن سيرين: إنه كان فيه حلقة من حديد، فأراد أنس أن يجعل مكانها حلقة من ذهب أو فضة، فقال له أبو طلحة: لا تغيرن شيئا صنعه رسول الله ﷺ فتركه.
Bukhari narrated it in the Book of Drinks (5638) from Hasan bin Mudrik, who said, Yahya bin Hammad narrated to me, Abu Awana informed us from Asim al-Ahwal, who said, and then he mentioned it.His saying "nadar" refers to fine wood of any kind, and it has also been said that it is the best kind of wood for making vessels.
