Perform religious rituals carefully according to Islamic teachings; Take care in all aspects of life; Pay attention to detail; Follow instructions carefully; Be mindful when doing tasks.

This hadith is about the importance of performing ablution properly. It was narrated from Anas that a man came to the Prophet and told him that he had performed ablution but missed a spot the size of a fingernail where water had not reached. The Prophet then advised him to go back and perform it again properly. This teaches us that we should be careful when performing our religious rituals, such as wudu, and make sure we do them correctly according to Islamic teachings. We should also take care in all aspects of our lives, including cleanliness and hygiene, so as not to miss any important details or steps in order for us to be successful in our endeavors.
