A man came to the prophet and said, 'My brother has got loose motions. The Prophet ﷺ said, Let him drink honey." The man again (came) and said, 'I made him drink (honey) but that made him worse.' The Prophet ﷺ said, 'Allah has said the Truth, and the ʿAbdomen of your brother has told a lie." (See Hadith No. 88)  

جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنَّ أَخِي اسْتَطْلَقَ بَطْنُهُ فَقَالَ اسْقِهِ عَسَلاً فَسَقَاهُ فَقَالَ إِنِّي سَقَيْتُهُ فَلَمْ يَزِدْهُ إِلاَّ اسْتِطْلاَقًا فَقَالَ صَدَقَ اللَّهُ وَكَذَبَ بَطْنُ أَخِيكَ
