That the Prophet (ﷺ) said: "The disbeliever eats with seven intestines and the believer eats with one intestine."

This Hadith is Hasan Sahih.

He said: There are narrations on this topic from Abu Hurairah, Abu Sa'eed, Abu Basrah Al-Ghifari, Abu Musa, Jahjah Al-Ghifari, Maimunah, and 'Abdullah bin 'Amr.
Jami` at-Tirmidhi Book 25, Hadith 32
← Previous Hadith "The Messenger of Allah (ﷺ) took the hand of a leper and put it in the Qas'ah. Then he said: 'Eat in Allah's Name, trusting in Allah and relying upon Him.'"

This is a Gharib Hadith, we do not know of it except through the report of Yunus bin Muhammad, from Al-Mufaddal bin Fadalah, a Shaikh from Al-Basrah. There is another Shaikh from Al-Basrah named Al-Mufaddal bin Fadalah, who is more reliable han this one and more popular. Shu'bah reported this Hadith from Habib bin Ash-Shahid, from Ibn Buraidah: "That Ibn 'Umar took the hand of a leper" and the narration of Shu'bah is more appropriate to me and more correct.

Jami` at-Tirmidhi Book 25, Hadith 31 Next Hadith → "The Messenger of Allah (ﷺ) had a disbeliever as a guest. So the Messenger of Allah (ﷺ) ordered that a sheep be milked so he could drink. Then another was milked so he could drink, then another, so he drank until he had drank the milk of seven sheep. The he awoke the next morning and accepted Islam. The Messenger of Allah (ﷺ) ordered that a sheep be milked so he could drink its milk, then he ordered for another but he could not finish it. So the Messenger of Allah (ﷺ) said: 'The believer drinks with one intestine and the disbeliever drinks with seven.'"

This Hadith is Sahih Hasan Gharib as a narration of Suhail.
