Obey God’s commands; Worship only Him; Pray regularly; Give charity/zakah generously

This hadith is about Prophet Muhammad's instructions for Mu'adh when he was sent on a mission to Yemen. The Prophet asked him to invite people there to testify that none has the right of worship except Allah, and that he is Allah's Messenger. He also asked him to teach them about their five daily prayers, which are obligatory upon all Muslims, as well as paying zakat from their wealth. Zakat is a form of charity given by those who have wealth in order for it be distributed among those who are less fortunate. This hadith teaches us about our obligations towards God, such as testifying His Oneness and worshipping Him alone, as well as our obligations towards others such as praying regularly and giving charity generously. It also shows us how important it is for us Muslims not only practice these teachings ourselves but also spread them among others so they can benefit from them too.
