Sahih Muslim , Book 35, Hadith 6503 (USC-MSA) ⓘ

Anas reported that Allah's Messenger 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.

وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَفَّانُ، حَدَّثَنَا حَمَّادٌ، أَخْبَرَنَا ثَابِتٌ، عَنْ أَنَسٍ، أَنَّعليه وسلم دَخَلَ عَلَى رَجُلٍ مِنْ أَصْحَابِهِ يَعُودُهُ وَقَدْ صَارَ كَالْفَرْخِ ‏.‏ بِمَعْنَى حَدِيثِ حُمَيْدٍ غَيْرَ أَنَّهُ قَالَ ‏ "‏ لاَ طَاقَةَ لَكَ بِعَذَابِ اللَّهِ ‏" ‏ ‏.‏ وَلَمْ يَذْكُرْ فَدَعَا اللَّهَ لَهُ فَشَفَاهُ ‏.‏
