“The Messenger of Allah
(ﷺ) said to me: ‘What do you use as a laxative?’ I said: ‘The
Shubrum (spurge – Euphorb).’ He said: (It is) hot and powerful.’
Then
I used senna as a laxative and he said: ‘If anything were to
cure
death, it would be senna. Senna is a cure for death.’”
Sunan Ibn Majah Book 31, Hadith 26
