Wash vessels seven times if a dog drinks from them .

The Prophet Muhammad (PBUH) taught us the importance of cleanliness and hygiene. He advised us to wash any vessel that a dog has drunk from seven times in order for it to be purified and considered clean again. This is because dogs are considered impure animals according to Islamic teachings, so washing the vessel is necessary in order for it to be used again without any worries of contamination or uncleanness. This hadith also teaches us the importance of being mindful and aware of our surroundings, as we should always take precautions when dealing with animals or other things that may not be considered pure according to Islamic teachings. We should also strive for cleanliness in all aspects of our lives, as this is an important part of living an Islamic lifestyle.
