In one narration the wording is: The narrator says: We were with the Prophet (peace and blessings be upon him) when a man from among the Jews came, whose name was Tha'labah bin al-Harith. He said: "Peace be upon you, O Sayyiduna Muhammad (peace and blessings be upon him)." The Prophet (peace and blessings be upon him) said: "And upon you." The Jew said to the Prophet (peace and blessings be upon him): "You claim that in Paradise there will be food, drink and wives." The Prophet (peace and blessings be upon him) said: "Yes. Do you believe in the tree of musk?" He said: "Yes." The Prophet (peace and blessings be upon him) said: "Have you found mention of it in your Book?" He replied: "Yes." The Prophet (peace and blessings be upon him) said: "Then urine and janabah (sexual discharge) will be in the form of sweat, which will flow from beneath their locks of hair down to their feet, and it will be like musk (in fragrance)." Imam al-Tabarani recorded all of these narrations in al-Mu'jam al-Awsat, and he recorded something similar in al-Mu'jam al-Kabir.
Imam Ahmad also recorded it, and he recorded these words: "The man said: 'O Abu al-Qasim, do you not claim that the people of Paradise will eat and drink in it?' He had said to his companions: 'If he concedes this to me, then I will argue with him.'" The rest of the narration is as before.
Imam al-Bazzar recorded it; the narrators of Ahmad and al-Bazzar are the narrators of the Sahih, except Thumamah bin Uqbah, who is thiqah (trustworthy).
