O my son, I have heard the Messenger of Allah (ﷺ) say: The worst of guardians is the cruel ruler. Beware of being one of them. Ubaidullah said (to him out of arrogance): Sit you down. You are from the chaff of the Companions of Muhammad (ﷺ). A'idh said: Was there worthless chaff among them? Such worthless chaff appeared after them and among other people.
Sahih Muslim Book 33, Hadith 32

Sahih Muslim Book 33, Hadith 31 Next Hadith → One day the Messenger of Allah (ﷺ) stood among us (to deliver a sermon). He talked about the misappropriation of booty, and declared it to be a serious matter and a grave sin. Then he said: I shouldn't find that any of you should come on the Day of Judgment with a growling camel mounted on his neck, and should appeal to me for help saying:" Messenger of Allah, help me." and I should say: I have no authority to help you; I already communicated to you. I shouldn't find that any of you should come on the Day of Judgment with a bleating ewe mounted on his neck, and he should say to me:" Messenger of Allah, help me," and I should say: I have no authority to help you; I conveyed to you. I shouldn't find that one of you should come on the Day of Judgment with a Person crying loudly mounted on his neck, and he should say to me:" Messenger of Allah, help me," and I should say: I have no authority to help you; I conveyed to you. I shouldn't find that any one of you should come on the Day of Judgment with fluttering clothes wrapped round his neck and he should say to me:" Messenger of Allah, help me," and I should say: I have no authority to help you; I conveyed to you. I shouldn't find that any of you should come on the Day of Judgment with a heap of gold and silver placed on his neck and he should say to me:" Messenger of Allah, help me." and I should say: I have no authority to help you; I already conveyed to you (the warning from the Almighty).
