Sa'd bin Abu Waqqas (May Allah be pleased with him) reported
The Messenger of Allah (ﷺ) came to visit me when I had a severe pain. I said: "I am suffering from such trouble as you are observing. I am a wealthy man and the only heir of mine is my daughter." (Then Sa'd narrated the whole incident).[Al-Bukhari and Muslim].
