Sahih Muslim | Book 35 | Hadith Number 6503
Narrated by Anas
Anas reported that Allah's Messenger (may peace be upon him) visited a person from amongst his Companions who had grown as feeble as the chicken. The rest of the hadith is the same, but with this variation that he (the Holy Prophet) said: You have not power enough to undergo the torment imposed by Allah. And there is no mention of: He supplicated Allah for him and He cured him.
