It was narrated that Abu Saeed Al-Khudri said: “It was said: ‘Messenger of Allah صلی اللہ علیہ وآلہ وسلم, you perform Wudu from the well of Buda’ah when it is a well into which the bodies of dogs, menstrual rags and garbage are thrown?’ He said: ‘Water is pure and it is not made impure by anything.” (Hasan)
