Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) was asked: "Can we perform ablution from the well of Budā‘ah, which is a well into which menstrual pads, dead dogs and stinky things are thrown?" He replied: "Water is pure and nothing makes it impure." Authentic hadith - An-Nasaa’i - Narrated by Abu Daoud - Narrated by Ahmad
