It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said: I entered one of the orchards of Madinah with the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) began eating green unripe dates (busr). Then he said: "Eat, O Ibn Umar." I said: "O Messenger of Allah! I have no desire for it." He (peace and blessings be upon him) said: "You have no desire for it? Yet this is the first food that the Messenger of Allah (peace and blessings be upon him) has eaten in four days."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Salim (may Allah have mercy on him) except al-Wazi' bin Nafi', and Ali bin Thabit is alone in narrating it."
