" The Messenger of Allah (may Allah’s peace and blessings be upon him) was asked about water that was frequented by animals and beasts of prey. He said: ""If there is enough water to fill two pitchers, then it will bear no impurity."" [Ibn Maajah]"
"عن عبد الله بن عمر -رضي الله عنهما- قال: سُئِلَ رسول الله -صلى الله عليه وسلم- عن الماء وما يَنُوبُهُ من الدواب والسِّبَاعِ، فقال -صلى الله عليه وسلم-: «إذا كان الماء قُلَّتين لم يحمل الخَبَثَ». [صحيح.] - [رواه أبو داود .]"
