This hadith is about the length of a month according to the teachings of Prophet Muhammad. It was narrated from several people including his companion, Muhammad bin Sad, who said that his father heard it directly from the Prophet himself. He said that "the month is like this and like this and like this," meaning twenty-nine days long. This hadith teaches us that we should follow what our beloved prophet taught us about how long a month should be and not rely on any other sources for information regarding religious matters.
