Pray humbly & devotedly according to Islamic teachings

This hadith speaks to the importance of prayer in Islam, as it is reported that the Prophet Muhammad (PBUH) was seen with a trace of clay on his forehead and nose after completing prayer. This suggests that he had been prostrating himself in prayer, which is an important part of Islamic worship. It also shows the importance of humility in worship, as clay is often associated with humility and submission to God's will. Additionally, this hadith serves as an example for Muslims to follow when engaging in their own prayers - they should strive for humility and devotion when worshipping God.
