It is narrated from Sayyidah Asma' bint Abi Bakr al-Siddiq (may Allah be pleased with them both) that she said: A boil appeared on my neck, and I mentioned it to the Prophet (peace and blessings be upon him). He (peace and blessings be upon him) said: "Lance it (open it); do not leave it in such a state that it begins to eat the flesh and suck the blood." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Qatadah bin al-Nu'man (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When Allah Almighty loves a servant, He protects him from the world (and its contaminations), just as one of you keeps his sick person away from water (so that it does not harm him)." This hadith is sahih (authentic) on the condition of Imam Bukhari, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: I fell ill, and my family made me abstain from everything, even water. One night I became very thirsty and no one was with me. I went near a hanging waterskin and drank a sip of water from it. In the morning I got up completely healthy, and I could feel the blessing of that one sip in my body. Sayyidah Aishah (may Allah be pleased with her) used to say: "Do not make the sick person abstain (strictly) from anything." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that he visited a man named al-Muqanna' in his illness and said: "I will not leave until he has cupping (hijamah) done, for I heard the Messenger of Allah (peace and blessings be upon him) saying: 'Indeed, there is cure in it.'" This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it!

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "(On the Night of the Ascension) I did not pass by any assembly of angels except that they ordered me to have cupping (hijamah) done." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) used to have cupping (hijamah) done on the 17th, 19th and 21st (of the lunar month). This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he said to Nafi': "O Nafi'! My blood is agitated, so find me a cupper (hajjam), and if possible let him be gentle; do not bring an old man or a small boy, for I heard the Messenger of Allah (peace and blessings be upon him) saying: 'Cupping (hijamah) on an empty stomach is better; in it there is cure and blessing; it increases the intellect and the memory. So have cupping done with the blessing of Allah on Thursday, and avoid it on Friday, Saturday and Sunday. And have cupping done on Monday and Tuesday, for that is the day on which Allah Almighty relieved Ayyub (peace be upon him) of his trial. Leprosy (baras) and elephantiasis (judham) only appear on Wednesday or on the night of Wednesday, for Ayyub (peace be upon him) was afflicted with his trial on a Wednesday.'" All the narrators of this hadith are trustworthy, except for Uthman bin Ja'far, about whose reliability or criticism I have no knowledge.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever has cupping (hijamah) done on a Wednesday or a Saturday and then is afflicted with leprosy (white patches), let him blame no one but himself."

This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
