Follow instructions given by your elders/leaders even if you don't understand why they are giving them. Be respectful of your elders/leaders and obey their orders.

This hadith is about the Prophet Muhammad's instructions when he was intending to march from a place called Mina. He instructed that they should encamp the next day, and also mentioned something similar as a previous tradition but did not mention the opening words nor did he mention the words "Al Khaif, Al Wadi". Al Khaif means valley in Arabic. This hadith teaches us that we should follow instructions given by our leaders and elders, even if we don't understand why they are giving them. It also teaches us to be respectful of our elders and leaders, as well as being obedient to their orders.
