Be mindful and aware of prayer times; Strive for knowledge and understanding in faith; Pray Isha when moon sets on third night.

This hadith is about the timing of 'Isha' prayers, which is one of the five daily obligatory prayers in Islam. According to this hadith, An-Nu'man bin Bashir said that he was most knowledgeable about when to pray 'Isha'. He said that Prophet Muhammad used to pray it when the moon set on the third night of each month. This shows us how important it is for Muslims to be mindful and aware of prayer times and not miss them. It also teaches us that we should strive for knowledge and understanding in our faith so we can practice it correctly.
