Hadith: I visited the Prophet (may Allah's peace and blessings be upon him) while he was in pain because of fever, so I touched him

عن ابن مسعود رضي الله عنه قال: دخلتُ على النبيِّ صلى الله عليه وسلم وهو يُوعَكُ، فَمَسَسْتُهُ، فقلتُ: إنّكَ لَتُوعَكُ وَعَكًا شَدِيدًا، فقالَ: «أجَلْ، إنِّي أُوعَكُ كما يُوعَكُ رَجُلانِ منكُم».
[صحيح] - [متفق عليه]

Ibn Mas‘ūd (may Allah be pleased with him) reported: I visited the Prophet (may Allah's peace and blessings be upon him) while he was in pain because of fever, so I touched him and said: "You are in great pain from raging fever." He said: "Indeed, the pain I feel from fever is like the pain that two men from among you might get."
[Authentic hadith] - [Narrated by Bukhari & Muslim]

Explanation

Ibn Mas‘ūd (may Allah be pleased with him) recalls that he visited the Prophet (may Allah's peace and blessings be upon him) while he was in pain from acute sickness. He stretched out his hand and said: "O Messenger of Allah, you are severely sick." The Prophet (may Allah's peace and blessings be upon him) informed him that his sickness is as severe as the sickness of two men among them so that he would achieve the highest degree of patience.
