Pour water over your head thrice using both hands and then rub each side with one hand each.

This hadith is about ritual purification for those who are in a state of junub, which is a state of ritual impurity. According to this hadith, when someone is junub, they should pour water over their head three times using both hands. Then they should rub the right side of their head with one hand and then rub the left side with the other hand. This process helps to cleanse oneself from any form of impurity and restore purity so that one can perform religious duties such as prayer or fasting. It also teaches us to be mindful about our physical cleanliness as well as spiritual purity.
