From Sahih Muslim (Hadith 2243):
Abu'l-Hayyaj al-Asadi told that 'Ali (b. Abu Talib) said to him:Should I not send you on the same mission as Allah's Messenger (ﷺ) sent me? Do not leave an image without obliterating it, or a high grave without levelling It. This hadith has been reported by Habib with the same chain of transmitters and he said: (Do not leave) a picture without obliterating it
