Take care in performing one's ablutions correctly; Strive for perfection in all aspects of life including worship; Follow advice given by the Prophet Muhammad PBUH .

This hadith is about the importance of perfecting one's wudu before prayer. It was narrated by Jabir bin Abdullah al-Ansari that Umar bin al-Khattab told him that the Prophet Muhammad saw a man doing wudu for Zuhr prayer but noticed he had missed a spot the size of a toenail. The Prophet advised him to go back and do his wudu properly before praying. This teaches us that we should take care in performing our ablutions correctly so as not to miss any part of it when preparing for prayer. We should strive for perfection in all aspects of our lives including our worship so as not to miss out on any blessings from Allah SWT.
