It was narrated that Asma’ bint ‘Umais said:
“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.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ عَبْدِ الْحَمِيدِ بْنِ جَعْفَرٍ، عَنْ زُرْعَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ مَوْلًى، لِمَعْمَرٍ التَّيْمِيِّ عَنْ مَعْمَرٍ التَّيْمِيِّ، عَنْ أَسْمَاءَ بِنْتِ عُمَيْسٍ، قَالَتْ قَالَ لِي رَسُولُ اللَّهِ ﷺ " بِمَاذَا كُنْتِ تَسْتَمْشِينَ " . قُلْتُ بِالشُّبْرُمِ قَالَ " حَارٌّ جَارٌّ " . ثُمَّ اسْتَمْشَيْتُ بِالسَّنَى . فَقَالَ " لَوْ كَانَ شَىْءٌ يَشْفِي مِنَ الْمَوْتِ كَانَ السَّنَى وَالسَّنَى شِفَاءٌ مِنَ الْمَوْتِ " .
