Ali bin Ms'hr علي بن مسهر · The Book of Purification

"The Messenger of Allah (ﷺ) said: 'If a dog licks the vessel of any one of you, let him throw (the contents) away and wash it seven times.'" Abu 'Abdur-Rahman (An-Nasa'i) said: I do not know any one who followed 'Ali bin Mushir in narrating it with: "Let him throw it away."
