It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "Among the trees, there is a tree which is like a Muslim (can you tell which tree that is?)" People presented their own opinions, and I wanted to say that it is the date-palm tree, but then the Prophet (peace and blessings be upon him) himself said that it is the date-palm tree.
