Follow Islamic teachings on keeping oneself clean even when using perfumes or other fragrances for personal grooming purposes .

This hadith highlights the importance of cleanliness in Islam, which is a fundamental part of faith for Muslims. In this hadith, Umar ibn al-Khattab noticed the smell of perfume coming from Kathir ibn as-Salt and asked him about it. When he was told that he had matted his hair with perfume, Umar instructed him to go to a Sharaba - which is a ditch at the base of a date palm - and rub his head until it is clean. This shows us how important cleanliness is in Islam, even when using perfumes or other fragrances for personal grooming purposes; we must ensure that our bodies are kept clean at all times according to Islamic teachings. Furthermore, this hadith also teaches us about humility; despite being an important figure in society, Kathir did not hesitate or argue when Umar gave him instructions on how he should groom himself according to Islamic teachings but instead followed them without question or hesitation.
