Undesirability of Drinking directly from the mouth of a Water-Skin
Abu Sa`id Al-Khudri (May Allah be pleased with him) reported: Messenger of Allah (PBUH) forbade turning the water-skin upside down and drinking directly from its mouth.[Al-Bukhari and Muslim].


Commentary:
Messenger of Allah (PBUH) has forbidden us to drink water from the mouth of a water-skin or something similar to it because some harmful insect in the water-skin may flow into the stomach. So, instead of drinking direct from the mouth of the water-skin, it is better to pour it into a drinking vessel in order to shun any possible harm.

باب كراهة الشرب من فم القربة ونحوها
وبيان أنه كراهة تنزيه لا تحريم
عن أبي سعيدٍ الخدْرِيِّ رضي اللَّه عنه قال نَهَى رسول اللَّه صَلّى اللهُ عَلَيْهِ وسَلَّم عنِ اخْتِنَاثِ الأَسْقِيَةِ . يعنى : أَنْ تُكسَرَ أَفْوَاهُها ، وَيُشْرَب منها . متفقٌ عليه .
