What does Islam say about the treatment of the sick?
Islam places a strong emphasis on taking care of the ill and the sick in one’s community
The Prophet Muhammad (peace be upon him) encouraged Muslims to visit the sick:
'When a person performs a proper wudhu (ablution) and then goes to visit his sick Muslim brother with the intention of gaining reward, then he will be kept far away from the Fire of Hell Fire by a distance equivalent of Sixty years.' (Abu Dawood)
Whoever visits a sick person (for the pleasure of Allah), a Caller from the skies announces: You are indeed blessed and your walking is blessed and you have (by this noble act) built yourself a home in Jannah.' (Ibn Maajah)
'When you visit a sick person or (go to the home of) someone who has died, then speak only what is good, for the angels say 'amen'to whatever you will say.' (Sahih Muslim)
The Messenger of Allah (the Prophet Muhammad peace be upon him) has ordered us to visit the sick, to follow the funeral (of a dead believer), respond to the sneezer (i.e., by saying to him: Yarhamuk-Allah after he says: Al-hamdu lillah), to help those who vow to fulfill it, to help the oppressed, to accept the invitation extended by the inviter; and to promote greetings (i.e., saying As-Salamu `Alaikum).(Al-Bukhari and Muslim)
'When you visit a sick person, speak in a reassuring way to him (about his age and his life).' (For instance, tell him, 'Alhamdulillah, your health has improved' or 'Inshaa Allah (God-willing) you will get better soon.') Saying this will not delay what is predestined, but it will certainly make him feel happy.' (Tirmidhii, Ibn Maajah)
I heard the Messenger of Allah (the Prophet Muhammad, please be upon him) saying, "When a Muslim visits a sick Muslim at dawn, seventy thousand angels keep on praying for him till dusk. If he visits him in the evening, seventy thousand angels keep on praying for him till the morning; and he will have (his share of) reaped fruits in Jannah."(At- Tirmidhi).
The Prophet Muhammad (peace be upon him) also said:
The Messenger of Allah (peace be upon him) said, "Every Muslim has five rights over another Muslim (i.e., he has to perform five duties for another Muslim): to return the greetings, to visit the sick, to accompany funeral processions, to accept an invitation, to respond to the sneezer [i.e., to say: 'Yarhamuk-Allah (may Allah bestow His Mercy on you),' when the sneezer praises Allah]." (Al-Bukhari and Muslim).
The Messenger of Allah (peace be upon him) said, "Visit the sick, feed the hungry, and (arrange for the) release of the captive.'(Al-Bukhari)
The Prophet Muhammad (peace be upon him) used visitation to the sick to pray for them:
When the Prophet (peace be upon him) visited any ailing member of his family, he would touch the sick person with his right hand and would supplicate: "Allahumma Rabban-nasi, adhhibil-ba'sa, washfi, Antash-Shafi, la shifa'a illa shifa'uka, shifaan la yughadiru saqaman [O Allah! the Rubb of mankind! Remove this disease and cure (him or her)! You are the Great Curer. There is no cure but through You, which leaves behind no disease]." (Al-Bukhari and Muslim).
The Prophet (peace be upon him) said, "He who visits a sick person who is not on the point of death and supplicates seven times: As'alullahal-'Azima Rabbal-'Arshil-'Azimi, an yashfiyaka (I beseech Allah the Great, the Rubb of the Great Throne, to heal you), Allah will certainly heal him from that sickness." (Abu Dawud and At- Tirmidhi).
The Prophet (peace be upon him) visited a bedouin who was sick. Whenever he visited an ailing person, he would say, "La ba'sa, tahurun in sha' Allah [No harm, (it will be a) purification (from sins), if Allah wills]." (Al-Bukhari).
