Obey Allah's messenger , Show respect when hearing news about death .

This hadith speaks of the Prophet Muhammad's reaction when he was told that three of his companions, Ibn Haritha, Ja'far b. Abu Talib and Abdullah b. Rawaha were killed. He showed signs of grief and a man came to him mentioning that Ja'far's women were lamenting. The Prophet then commanded him to go and forbid them from doing so but they did not obey him. He then commanded him a second time but they still did not obey him, so 'A'isha thought that the Prophet wanted her to throw dust in their mouths as punishment for disobeying his orders. This hadith teaches us about mourning in Islam which is discouraged by Allah as it can lead people away from faith and piety if done excessively or with certain rituals such as wailing or tearing one’s clothes which are forbidden in Islam according to some scholars. It also teaches us about obedience towards Allah’s Messenger which is an important part of faith since obeying Allah means obeying His Messenger too, even if we don't understand why something has been ordered by Him at first glance because it could be for our own benefit even though we may not realize it at first sight due to our limited knowledge or understanding compared with His infinite wisdom and knowledge .
