Follow the teachings of Prophet Muhammad PBUH regarding cleanliness and purity when engaging in religious activities or using items related to religion .

This hadith, narrated by Ibn 'Abbas, teaches us about the purification of tanned skin. Tanning is a process in which animal hides are treated with chemicals and oils to make them into leather. According to this hadith, any skin that has been tanned is considered to be purified. This means that it can be used for religious purposes such as making prayer mats or clothing for worshipers. It also implies that tanning can help remove impurities from the animal hide and make it suitable for use in religious activities. This hadith serves as an important reminder of the importance of cleanliness and purity when engaging in religious activities or using items related to religion.
