He will then say: “My Lord, if You would permit me, I would feed the people of Paradise and give them drink, and nothing of what I possess would diminish. He shall have from among the ḥūr al-ʿayn seventy-two wives in addition to those who were his wives in this world, and the space taken up by just one of them would measure a mile on earth.”

This report is unique to Aḥmad; it is gharīb and its chain is broken (1).

It has a corroborating narration from ʿUbādah ibn al-Ṣāmit.
Imam Aḥmad said: Yaʿmar ibn Bishr narrated to us; ʿAbd Allāh ibn al-Mubārak narrated to us; Rushdīn ibn Saʿd (2) narrated to us; Abū Hāniʾ al-Khawlānī told me, from ʿAmr ibn Mālik al-Janabī, that Faḍālah ibn ʿUbayd and ʿUbādah ibn al-Ṣāmit related that the Messenger of Allah ﷺ said:

“When the Day of Resurrection comes and Allah—Exalted is He—has finished judging between all creatures, two men will remain. Allah will command that they both be taken to the Fire. As they are being led away, one of them will look back. The Compeller, Exalted, will say, ‘Bring him back.’ They will bring him back and He will say, ‘Why did you look back?’ He will reply, ‘I was hoping that You would admit me to Paradise.’ So Allah will command that he be taken to Paradise. The man will then say, ‘Allah—Exalted is He—has given me so much that if I were to feed the inhabitants of Paradise, nothing of what I possess would decrease.’”
The Messenger of Allah ﷺ was seen beaming with joy when he related this. It is reported only by Aḥmad (3).

Imam Aḥmad also said: Abū Muʿāwiyah narrated to us; al-Aʿmash narrated to us, from Thumāmah ibn ʿUqbah, from Zayd ibn Arqam, who said: A man from the Jews came to the Prophet ﷺ and said, “O Abū al-Qāsim, do you not claim that the people of Paradise eat and drink therein?” The Jew then said to his companions, “If he admits this, I will defeat him.” The Messenger of Allah ﷺ replied, “Indeed—by Him in whose hand is my soul—each one of them will be given the strength of a hundred men for eating, drinking, passion, and intercourse.” The Jew said, “But whoever eats and drinks must relieve himself.” The Prophet ﷺ answered, “The relief of any one of them will be perspiration that flows from their skins with a fragrance like musk, whereupon the belly becomes flat.”

Aḥmad later narrated it through Wakīʿ, from al-Aʿmash, [from] Thumāmah: “I heard Zayd ibn Arqam …” and he mentioned it.

Al-Nasāʾī likewise recorded it from ʿAlī ibn Ḥujr, from ʿAlī ibn Mushir, from al-Aʿmash, and Abū Jaʿfar al-Rāzī narrated it from al-Aʿmash as well, giving the same content. In his version the Jew says, “Whoever eats and drinks must relieve himself, yet there is no impurity in Paradise.” The Messenger of Allah ﷺ replied, “The relief of any one of them will be a perspiration that flows from their skins like the scent of musk, after which the belly lies flat.”

Al-Ḥāfiẓ al-Ḍiyāʾ said: “In my view this ḥadīth satisfies the criteria of Muslim, for Thumāmah is reliable and he explicitly stated that he heard it from Zayd ibn Arqam (4).”
