The Messenger of Allah ﷺ said, "Allah has not sent down any disease without also sending down a cure for it. Some of you are ignorant of it, and some of you know it."
حدثنا عبد الله قال قرأت على أبي حدثنا علي بن عاصم أخبرني عطاء بن السائب قال أتيت أبا عبد الرحمن فإذا هو يكوي غلاما قال قلت تكويه قال نعم هو دواء العرب
قال رسول الله ﷺ إن الله عز وجل لم ينزل داء إلا وقد أنزل معه دواء جهله منكم من جهله وعلمه منكم من علمه
Its isnad is hasan, for Ali bin Asim was among those who heard from Ata bin Saaib late in his life. Abu Abdul-Rahman is Sulami. The hadith has already been mentioned, without the account of the cauterization, with sahih chains, the last of them being 4236.
