Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: A man from Banu Amir, who used to practise medicine and treatment, came to the Prophet (peace and blessings be upon him). He said to the Prophet (peace and blessings be upon him): "O Sayyiduna Muhammad (peace and blessings be upon him)! You say certain things; would you like me to treat you?" The narrator says: The Prophet (peace and blessings be upon him) called him and said to him: "Would you like me to treat you?" He said: "Go ahead." At that time there was a tree and a date palm there. The Prophet (peace and blessings be upon him) called one tree among them, and it came towards him and prostrated, then it raised its head and prostrated again, then raised its head and prostrated, until, prostrating in this way, it reached him and came and stood in front of him. The Prophet (peace and blessings be upon him) said to it: "Go back to your place." It went back to its place. That man said: "By Allah! After this, whatever you say, I will never call you a liar regarding anything." Then that man said: "O Amir bin Sa'sa'ah! By Allah! After this, whatever this man says, I will never call him a liar regarding anything." The narrator says: 'Idhq means a date palm.
Abu Ya'la recorded it, and its narrators are the narrators of the Sahih, except for Ibrahim bin al-Hajjaj al-Shami, and he is thiqah (trustworthy).
