The Messenger of Allah ﷺ said, "There are three things in which lies a cure for every disease except death, senna and sanut."
قال رسول الله ﷺ: ثلاث فيهن شفاء من كل داء إلا السام، السنا والسنوت.
Narrated by Nasai in Kubra (7533), Abu Naeem in Tibb (178, 612), and Diya Maqdisi in Mukhtara (6/236), all of them through Hatim bin Ismail, from Muhammad bin Umara, from Abdullah bin Abdullah bin Abu Talha, from Anas bin Malik, who said, and then he related it. Muhammad, meaning bin Umara, said, "I forgot the third one." They said, "Messenger of Allah, we already know this sena, but what is the sanoot?" He said, "If Allah willed, He would have made you know it too."Its chain of transmission is hasan because of Hatim bin Ismail and his teacher Muhammad bin Umara, for both of them make the hadith hasan. As for Muhammad bin Umara's statement, "I forgot the third one," it was likely the black seed, for it has come in the sahih, "In the black seed there is a cure for every disease except death," as will come later.Similar in meaning is what was narrated from Asma bint Umays, who said, the Messenger of Allah ﷺ said to me, "What have you been treating yourself with?" She said, "With shubrum." He said, "It is hot and harsh." Then she said she treated herself with sena, and he said, "If anything could cure death, it would be sena," or, "Sena is a cure for death." Narrated by Ahmad (27080), and this is his wording, Tirmidhi (2081), and Ibn Majah (3461). Its chain of transmission contains disorder, and among its narrators are unknown figures. That is why Tirmidhi said, "This is a strange hadith," meaning daif.Likewise, what was narrated from Ibrahim bin Abu Abla is not sound. He said, "I heard Abu Ubayy bin Umm Haram, who had prayed with the Messenger of Allah ﷺ toward both qiblahs, say, I heard the Messenger of Allah ﷺ say, 'You should use sena and sanoot, for in them is a cure for every disease except death.'" It was said, "Messenger of Allah, and what is death?" He said, "Death is death." Amr said, Ibn Abu Abla said, "Sanoot is sabt." Others said, "Rather it is the honey found in the skins of clarified butter," as in the poet's saying, "They are like clarified butter mixed with sanoot, with no deceit in them, and they protect their neighbor from being wronged."Narrated by Ibn Majah (3457) and Hakim (4/201), both from the hadith of Amr bin Bakr Saksaki, who said, Ibrahim bin Abu Abla narrated to us, and then he related it. Hakim said, "This is a hadith sahih in its chain of transmission, though the two of them did not include it." Dhahabi challenged him on this, saying, "Ibn Hibban accused Amr of fabrication, and Ibn Adi said he has objectionable narrations." Aqeeli said, "His hadith is not preserved." Given this state of affairs, Hakim's grading it sahih is evidence of his laxity, for Dhahabi and others have confirmed that he included fabricated hadiths in his book.As for "sanoot," it is honey, as mentioned before, and "sena" is a plant used to treat those suffering from constipation.
