Trusting in Allah's guidance .

This hadith teaches us about the length of a month in Islam. The Prophet Muhammad ﷺ taught that the month is thirty days long and that Muslims should not use computation to determine the length of a month. This hadith also highlights an important aspect of Islamic teachings, which is that even though we are an unlettered ummah, meaning we do not have access to books or written records, we still have access to knowledge through our Prophet ﷺ who was sent as a teacher and guide for all mankind. We can learn from this hadith how important it is for us to trust in Allah's guidance and teachings rather than relying on our own understanding or calculations.
