It is narrated from al-Walid bin Abd al-Rahman bin Awf, from his father, from his grandfather, that the Messenger of Allah (peace and blessings be upon him) said: "Do not force your sick ones to eat and drink, for Allah, the Mighty and Majestic, feeds them and gives them drink." This hadith has a sahih (authentic) chain of narration and all its narrators are from Madinah, but the two Shaykhs (Bukhari and Muslim) did not record it. We also have, on this topic, the report of Imam Malik from Nafi', in narrating which from him Muhammad bin al-Walid al-Yashkuri is alone.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade impure (khabith) medicine. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it. Impure medicine means, without doubt, wine itself. And the two Shaykhs agreed upon this narration of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him): "Indeed, Allah Almighty has not placed your cure in what He has made unlawful for you." And Muslim alone also recorded this hadith: "Indeed, it (wine) is not a medicine; rather, it is itself a disease."

It is narrated from Sayyiduna Abdur-Rahman bin Uthman al-Taymi (may Allah be pleased with him) that a physician mentioned a medicine in the presence of the Messenger of Allah (peace and blessings be upon him) and spoke of putting a frog in it, so the Prophet (peace and blessings be upon him) forbade killing it. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Every person has in his head some veins of leprosy which stir; when they become agitated, Allah Almighty sends a cold (catarrh) upon him, so do not treat the cold."

It is narrated from Sayyiduna Suhayb (may Allah be pleased with him) that he said: I came to the Prophet (peace and blessings be upon him) and there were dates and bread placed before him. He (peace and blessings be upon him) said: "Come near and eat." So I began eating the dates. He (peace and blessings be upon him) said: "You are eating dates while you have an eye inflammation?!" I said: O Messenger of Allah, I am chewing on the other side. At that the Prophet (peace and blessings be upon him) smiled. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Beware of sitting in the sun, for it wears out the garment, makes the odour offensive, and brings out hidden disease."
