Dress appropriately when engaging in any religious activity or practice .

The hadith reported by Abu Hurairah states that it is not permissible to pray in a single garment of which no part comes over the shoulders. This means that when praying, one should be properly clothed and covered, with at least some part of the clothing covering the shoulders. This hadith teaches us about modesty and respect for oneself and for Allah when engaging in prayer. It also emphasizes the importance of being properly dressed when engaging in any religious activity or practice, as it shows respect for Allah and reverence towards Him. Furthermore, this hadith serves as an example of how we should conduct ourselves during prayer; we should be mindful of our appearance and dress appropriately so as to show proper respect for Allah's presence.
