Maintain a high level of cleanliness and purity when praying; Make sure your clothes are free from dirt or stains before beginning prayer; Strive for excellence in all aspects of life including physical appearance and hygiene.

This hadith speaks to the importance of cleanliness and purity in prayer. It was narrated by 'Ubaidullah bin Abdullah bin Aqram that his father said he prayed with the Messenger of Allah and noticed that his armpits were very white. This indicates that even though we may not be able to see it, it is important for us to maintain a high level of cleanliness and purity when we pray. We should make sure our clothes are clean and free from any dirt or stains before we begin our prayers so that we can focus on worshipping Allah without any distractions. Additionally, this hadith also serves as a reminder for us to strive for excellence in all aspects of our lives, including our physical appearance and hygiene.
