With regard to the sickness that you have, if you bear it with patience and seek reward, Allaah will make your sickness an expiation for your sins.
It was narrated from Abu Sa’eed al-Khudri and Abu Hurayrah that the Prophet (peace and blessings of Allaah be upon him) said:
“No tiredness, exhaustion, worry, grief, distress or harm befalls a believer in this world, not even a thorn that pricks him, but Allaah expiates some of his sins thereby.” Narrated by al-Bukhaari, 5318 and Muslim, 2573.
Some remedies that are prescribed in sharee’ah include the following:
1 – Honey. Allaah says (interpretation of the meaning):
“Then, eat of all fruits, and follow the ways of your Lord made easy (for you).” There comes forth from their bellies, a drink of varying colour wherein is healing for men. Verily, in this is indeed a sign for people who think” [al-Nahl 16:69]
2 – Indian aloes wood (al-‘ood al-hindi).
It was narrated that Umm Qays bint Muhsin said:
I heard the Prophet (peace and blessings of Allaah be upon him) say: “You should use Indian aloes wood for in it are seven cures.” Narrated by al-Bukhaari, 5368; Muslim, 287.
3 – Cupping (hijama).
It was narrated from Ibn ‘Abbaas that the Messenger of Allaah (peace and blessings of Allaah be upon him) was treated with cupping when he was in a state of ihraam on his head for a migraine that he was suffering. Narrated by al-Bukhaari, 5374; Muslim, 1202.
Al-Bukhari included it in a chapter which he called: Chapter on cupping for migraines and headaches.
4 – Black seed.
It was narrated from Abu Hurayrah that the Prophet (peace and blessings of Allaah be upon him) said:
“In the black seed is healing for every disease except death.” Narrated by al-Bukhaari, 5364; Muslim, 2215.
Some du’aa’s from the saheeh Sunnah:
1 – It was narrated from ‘Uthmaan ibn Abi’l-‘Aas that he complained to the Messenger of Allaah (peace and blessings of Allaah be upon him) about a pain in his body that he had suffered from the time he became Muslim. The Messenger of Allaah (peace and blessings of Allaah be upon him) said to him:
“Put your hand on the part of the body that hurts and say Bismillaah (in the name of Allaah) three times. And say seven times: A’oodhu Billaahi wa qudratihi min sharri ma ajid wa uhaadhir (I seek refuge in Allaah and His power from the evil of what I feel and worry about).” Narrated by Muslim, 2202.
2 – It was narrated from ‘Aa’ishah (may Allaah be pleased with her) that when the Messenger of Allaah (peace and blessings of Allaah be upon him) came to a sick person or a sick person was brought to him, he would say:
“Adhhib al-ba’s Rabb an-naas, wa’shfi anta al-Shaafi, laa shifaa’a illa shifaa’uka shifaa’an laa yughaadir saqaman (Take away the pain, O Lord of mankind, and grant healing, for You are the Healer, and there is no healing but Your healing that leaves no trace of sickness).” Narrated by al-Bukhaari, 5351, Muslim, 2191.
You should also recite al-Faatihah and al-Mu’awwidhaat, and in the whole Qur’aan there is healing, as Allaah says (interpretation of the meaning):
“And We send down of the Qur’aan that which is a healing and a mercy to those who believe (in Islamic Monotheism and act on it), and it increases the Zaalimoon (polytheists and wrongdoers) nothing but loss” [al-Isra’ 17:82]
3 – It was narrated from Abu Sa’eed al-Khudri (may Allaah be pleased with him) that some of the companions of the Prophet (peace and blessings of Allaah be upon him) came to one of the Arab tribes. They asked them for hospitality but they refused to welcome them. Whilst they were like that, the chief of that tribe was stung. They said: ‘Do you have any remedy or someone who can recite ruqyah?’ They said: ‘You did not offer us hospitality, so we will not do anything until you give us something in return.’ Then they agreed upon a flock of sheep. Then he started to recite the Essence of the Qur’aan – i.e., Soorat al-Faatihah – and he collected his saliva and spat at him (at the site of the injury), and he recovered. The sheep were brought and they (the companions) said: We will not take them until we ask the Prophet (peace and blessings of Allaah be upon him). So they asked him and he smiled and said: “How did you know that it is a ruqyah? Take them and give me a share of them.” Narrated by al-Bukhaari, 5404; Muslim, 2201.
4 – It was narrated from ‘Aa’ishah (may Allaah be pleased with her) that the Prophet (peace and blessings of Allaah be upon him) used to recite al-mu’aawidhaat and blow over himself during his final illness, and when he became too ill (to do that), I used to recite them and blow over him and wipe his hand on him for blessing.
Mu’ammar said: I asked al-Zuhri how he used to blow and he said: He used to blow on his hands then wipe his face with them. Narrated by al-Bukhaari, 5403; Muslim, 2192.
And Allaah knows best
