Mustadrak al-Hakim 7854

Abū Bakr Muḥammad b. Isḥāq > Abū al-Muthanná > Musaddad > Yaḥyá b. Saʿīd > Saʿd b. Isḥāq b. Kaʿb b. ʿUjrah > Zaynab b. Kaʿb > Abū Saʿīd al-Khudrī > a man

A man said, "O Messenger of Allah, what is the matter with these diseases that afflict us?" He replied, "They are expiation for sins." Ubayy ibn Ka'b said, "O Messenger of Allah, even if they are few?" He said, "Yes, even if they are as little as a thorn prick or less." Ubayy then made a vow not to be separated from the pain until he died, so that it would not distract him from performing Hajj, Umrah, or Jihad in the cause of Allah Almighty, nor the obligatory congregational prayers. The Prophet said, "No man's skin was touched by it except that he found its heat until he died." – Sound Chain per Bukhārī and Muslim
