Be mindful of your reactions to unusual sounds or situations before making any judgments or decisions based on your initial reactions .

This hadith is about the sound of a man blowing a pipe and Ibn 'Umar's reaction to it. Nafi reported that when he was with Ibn 'Umar, he heard the sound of someone playing a pipe. In response, Ibn 'Umar mentioned another similar tradition. Abu Dawud commented that this tradition was more rejected than accepted. This hadith teaches us that we should be mindful of our reactions to unusual sounds or situations as they may not always be what they seem at first glance. We should take time to consider all possibilities before making any judgments or decisions based on our initial reactions.
