“I heard Abu Ubayy bin Umm Haram, who had
prayed with the Messenger of Allah (ﷺ) facing both the Qiblah,
saying: ‘I heard the Messenger of Allah (ﷺ) say: “You should
use senna and the Sannut, for in them there is healing for every
disease, except the Sam.” It was said: “O Messenger of Allah,
what is the Sam?” He said: “Death.”
(One of the narrators) ‘Amr said: “Ibn Abu ‘Ablah said: the ‘Sannut is dill.” Others said: “Rather, it is honey that is kept in a skin (i.e., receptacle) used for ghee.”*
