Sayyiduna Rafi' bin Khadij (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) came to Madinah while the people were doing ta'bir (pollination) of the palm trees. He (peace and blessings be upon him) said: "What are you doing?" They said: This is what we used to do. He (peace and blessings be upon him) said: "If you did not do it, it would be better." So they gave it up, and the dates came out poor. That was mentioned to him (peace and blessings be upon him), and he (peace and blessings be upon him) said: "I am only a human being. So when I command you with something concerning your religion, adopt it; and when I command you with something concerning your worldly affairs, then remember that I am only a human being."
