I heard Messenger of Allah ﷺ forbidding the drinking of water by bending the mouths of water skins, i.e., drinking from the mouths directly.  

البخاري:٥٦٢٦حَدَّثَنَا مُحَمَّدُ بْنُ مُقَاتِلٍ أَخْبَرَنَا عَبْدُ اللَّهِ أَخْبَرَنَا يُونُسُ عَنِ الزُّهْرِيِّ قَالَ حَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ أَنَّهُ سَمِعَ أَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولُ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَنْهَى عَنِ اخْتِنَاثِ الأَسْقِيَةِ قَالَ عَبْدُ اللَّهِ قَالَ مَعْمَرٌ أَوْ غَيْرُهُ هُوَ الشُّرْبُ مِنْ أَفْوَاهِهَا
