“The Messenger of Allah ﷺ forbade tipping up water skins in order to drink from their mouths.”  

نَهَى رَسُولُ اللَّهِ ﷺ عَنِ اخْتِنَاثِ الأَسْقِيَةِ أَنْ يُشْرَبَ مِنْ أَفْوَاهِهَا  

“The Messenger of Allah ﷺ forbade tipping up water skins. After the Messenger of Allah ﷺ had forbidden that, a man got up at night and tipped up a water skin, and a snake fell out of it onto him.”  

نَهَى رَسُولُ اللَّهِ ﷺ عَنِ اخْتِنَاثِ الأَسْقِيَةِ وَإِنَّ رَجُلاً بَعْدَمَا نَهَى رَسُولُ اللَّهِ ﷺ عَنْ ذَلِكَ قَامَ مِنَ اللَّيْلِ إِلَى سِقَاءٍ فَاخْتَنَثَهُ فَخَرَجَتْ عَلَيْهِ مِنْهُ حَيَّةٌ
