Be mindful of your prayers and make sure you are praying at the right times

This hadith is about the importance of knowing the times for prayers. It is narrated by 'Ali ibn Abi Talib, who said that he and his companions thought it was Fajr prayer time, but the Prophet Muhammad corrected them and said that it was actually Asr prayer time. This hadith teaches us to be mindful of our prayers and to make sure we are praying at the right times. We should also be humble enough to accept correction from others if we are wrong in our assumptions or beliefs. Additionally, this hadith shows us how important knowledge is in Islam; not only do we need to know when to pray, but also what type of prayer should be offered at each specific time.
