Follow what has been commanded by Allah and His messenger

This hadith is about the prohibition of Mut'a, which was forbidden by Allah's Messenger. According to this hadith, 'Ali b. Abil Talib told a person that they were led astray because Allah's Messenger forbade them from doing Mut'a as stated in another hadith transmitted on the authority of Yahya b. Malik. This shows us that it is important to follow what has been commanded by Allah and His messenger and not go against it or be led astray by others who may have different opinions or beliefs than us. It also teaches us to be mindful when we are engaging in activities and make sure they are permissible according to Islamic teachings so we can stay away from any form of sinning or wrong-doing.
