Did anyone other than Ibn ʿUmar narrate the Hadith, "Indeed, among trees there is a tree whose leaves do not fall, and it yields its fruit at all times," and if so, where was that mentioned and in which book?

The Hadith was not narrated in the books of Sunnah by anyone other than Ibn Umar, and all the chains of transmission (asanid) of the Hadith mentioned by Al-Ayni in his commentary on Al-Bukhari conclude with Ibn Umar, may Allah be pleased with them both.
