Sayyiduna Abdullah bin Umar (may Allah be pleased with him) narrates: Once we were sitting with the Prophet Muhammad (peace be upon him). During that time, "Jumar" (the gum of the date-palm tree) was brought, so the Prophet Muhammad (peace be upon him) said: There is a tree whose blessing is like that of a Muslim. Sayyiduna Abdullah bin Umar (may Allah be pleased with him) says: I thought that it would be the date-palm tree. Then I looked at those present, and I was the tenth person among ten people there, and I was the youngest among them. Therefore, I remained silent. The Prophet Muhammad (peace be upon him) said: It is the date-palm tree.
