Asma' bint 'Umais narrated that the Messenger of Allah ﷺ asked her what they used as a laxative. She said:

"Shubrum" He said: "It is hot and too strong." She said:"Then I used Senna as a laxative." So the Prophet ﷺ: "If there was anything that would have a cure for death in it, then it would have been Senna."

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ، حَدَّثَنَا عَبْدُ الْحَمِيدِ بْنُ جَعْفَرٍ، حَدَّثَنِي عُتْبَةُ بْنُ عَبْدِ اللَّهِ، عَنْ أَسْمَاءَ بِنْتِ عُمَيْسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ سَأَلَهَا " بِمَ تَسْتَمْشِينَ " . قَالَتْ بِالشُّبْرُمِ . قَالَ " حَارٌّ جَارٌّ " . قَالَتْ ثُمَّ اسْتَمْشَيْتُ بِالسَّنَا . فَقَالَ النَّبِيُّ ﷺ " لَوْ أَنَّ شَيْئًا كَانَ فِيهِ شِفَاءٌ مِنَ الْمَوْتِ لَكَانَ فِي السَّنَا " .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ . يَعْنِي دَوَاءَ الْمَشْىِّ .
