It is narrated from Hazrat Buraidah (may Allah be pleased with him) that when Hazrat Salman Farsi (may Allah be pleased with him) came to Madinah Munawwarah, he brought a platter of fresh dates to the service of the Noble Prophet (peace and blessings be upon him) and placed it before him. The Noble Prophet (peace and blessings be upon him) asked, "Salman! What is this?" He replied, "It is charity for you and your companions." The Noble Prophet (peace and blessings be upon him) said, "Take it away, we do not eat charity." He took it away, and the next day brought dates in the same manner and placed them before the Noble Prophet (peace and blessings be upon him) (the same question and answer took place, and he came again on the third day). The Noble Prophet (peace and blessings be upon him) asked, "Salman! What is this?" He replied, "This is a gift for you." The Noble Prophet (peace and blessings be upon him) included his companions (may Allah be pleased with them) in it as well. Then he (Salman) saw the Seal of Prophethood on the blessed back of the Noble Prophet (peace and blessings be upon him) and accepted faith. Since he was a slave of a Jew, the Noble Prophet (peace and blessings be upon him) bought him for a certain amount of dirhams and on the condition that the Muslims would plant a garden and work in it until it bore fruit. The Noble Prophet (peace and blessings be upon him) planted the saplings in that garden with his own blessed hands, except for one sapling which Hazrat Umar (may Allah be pleased with him) had planted, and in the same year all the trees bore fruit except for that one tree. The Noble Prophet (peace and blessings be upon him) asked, "What is the matter with this one?" Hazrat Umar (may Allah be pleased with him) replied, "O Messenger of Allah! I planted it." The Noble Prophet (peace and blessings be upon him) uprooted it and planted it himself, and it too bore fruit in the same year.
