I heard the Messenger of Allah ﷺ say, while I was a young boy, "The ajwa date and the tree are from Paradise."
حدثني يحيى بن سعيد حدثنا المشمعل حدثني عمرو بن سليم المزني أنه سمع
سمعت رسول الله ﷺ يقول وأنا وصيف يقول العجوة والشجرة من الجنة
Its isnad is sahih, it was mentioned previously at 15447 with the same chain and wording.
