Leave what causes you to have doubts for what does not cause doubts .

This hadith teaches us the importance of leaving behind things that cause us to doubt or be uncertain, and instead focusing on those things that do not cause us to doubt. The narrator of this hadith is Abu Al-Hawra' As-Sa'di who asked Hasan bin Ali what he had memorized from the Prophet Muhammad. Hasan bin Ali replied with a saying from the Prophet Muhammad which was “Leave that which makes you doubt for that which does not make you doubt”. This saying emphasizes the importance of avoiding things in life that can lead to confusion or uncertainty, and instead focusing on those things in life where we can be certain about our decisions. It is important for children to understand this concept as it will help them make wise decisions in their lives when faced with difficult choices.
