The Farewell Hajj

Muadh bin Jabal sleeps down the first part of night and wakes up when he takes his need of sleep and he recites what Allah made him recite.

When Muhammad S sent Muadh to Yaman, he said to him that he's going to a people who are a people of a scripture, so call them to become muslims. If they accept, then tell them allah has obligated ion them 5 prayers. If they accept then tell them allah has obligated for them to give zakeh to their poor. If they accept that then choose the average lamb or goat or whatever for slottering zakah. And do not oppress.
-Bukhari

Muhammad S says recruit them as soon as they become muslim.

Muhammad [SAW] said to Muadh that he (Muhammad S) may not see him again.

When Muadh came back, Muhammad had died. Muadh had some money and Umar told him to give it to Abu Bakr. Muadh refused because Muhammad told him to. Umar went to Abu Bakr to tell him to take some of Muadh's money. Abu Bakr refused, and then Muadh had a dream where he was being pullled toward hell and Umar was holding him back, soi Muadh gave all his money to Abu Bakr and Abu bakr gave it back and said it was Halal now, Inshalllah.

Muhammad S made Hajj and rode on his camel with humble riding equipment. A humble Hegg.
