Anas reported that a Jewish boy used to serve the Prophet, may Allah bless him and grant him peace. The boy became ill and the Prophet, may Allah bless him and grant him peace, went to visit him. He sat by his head and said, "Become a Muslim." The boy looked at his father who was also sitting by his head. His father said to him, "Obey Abu'l-Qasim (may Allah bless him and grant him peace)." So the boy became a Muslim. The Prophet, may Allah bless him and grant him peace, left saying, "Praise be to Allah who has saved him from the Fire!"

'A'isha (ra) said, "When the Messenger of Allah, may Allah bless him and grant him peace, came to Madina, Abu Bakr (ra) and Bilal (ra) came down with a fever. I visited them and asked, 'Father, how are you? Bilal, how are you?' When Abu Bakr's (ra) fever worsened, he said:"Every body is given the prayer to arise healthy among his people, yet death is nearer to him than his shoe-laces." And whenever Bilal’s (ra) fever subsided, he would recite, "Would that I know that I will ever spend a night in a valley surrounded by Izkhir and Jaleel (two kinds of sweet smelling grass). And that I will arrive one day to the waters of Majannah and observe (the mountains) Shamah and Tafeel" Ayshah (ra) went to the Prophet (ﷺ) M, and informed him of what transpired with these two men. Thereupon, he made this supplication: "O Allah, make us love Madinah as dearly as we love Makkah, or more than that. O Allah! Make it healthy for us and bless for us it sa' and mudd. And remove its fever putting it in al-Juhfah"

Ibn 'Abbas reported that the Prophet, may Allah bless him and grant him peace, went to visit a bedouin who was ill. When the Prophet, may Allah bless him and grant him peace, visited someone who was ill, he would say, 'There is no harm in it. It is a purification, Allah willing." That man then said, "A purification! No, rather it is a fever which boils (or appears) in an old man and will cause him to visit the graces." The Prophet, may Allah bless him and grant him peace, said, "Then yes (it is)".

'Abdullah ibn 'Amr ibn al-'As said, "Do not visit wine-drinkers when they are ill."

Al-Harith ibn 'Abdullah al-Ansari said, "I saw Umm ad-Darda' going to visit (a sick) Ansari man from the mosque and she was on her mount in an uncovered howdah."

Al-Qasim ibn Muhammad reported that one of the Companions of Muhammad lost his eyesight and people visited him. He said, "I used to look at the Prophet, may Allah bless him and grant him peace, but now that the Prophet, may Allah bless him and grant him peace, has died, by Allah, what has happened to my eyes is as easy for me to bear as one of the gazelles of Tibala (in Yemen)."

Anas said, "I heard the Prophet, may Allah bless him and grant him peace, say that Allah Almighty said, 'When I test him in his two precious ones (i.e. his eyes) and he is steadfast, I will repay him with the Garden.'"
