`Umar bin al-Khattab gave a speech and said: O people, we used to know you when the Prophet (ﷺ) was among us and revelation was coming down to him; Allah would tell us about you. But now the Prophet (ﷺ) has passed away and revelation has ceased, and now the way to judge you is this whoever among you shows us good conduct, we will think well of him and love him; whoever among you shows us bad conduct, we will think badly of him and hate him for that, and whatever is in your hearts is between you and your Lord. There was a time when I used to think that whoever learned the Qur`an, seeking thereby Allah and (the reward that) is with Him, would be rewarded in the Hereafter, but some men learned Qur`an seeking that which is with people. So seek Allah by learning Qur`an and by your good deeds. By Allah, I do not send my workers to strike you or seize your wealth; rather I send them to you to teach you your religion and Sunnah, whoever has done to him something other than that, let him refer it to me, for by the One in Whose hand is my soul, I shall surely grant him retaliation. `Amr bin al-`As stood up and said: O Ameer al Mu`mineen, do you think if one of the Muslims was in charge of some people and he disciplined one of them, would you allow that one to settle the score with him? He said: Yes, by the One in Whose hand is the soul of `Umar, I would not certainly allow him to settle the score with him. I saw the Messenger of Allah (ﷺ) do that with regard to himself. But do not strike the Muslims and thus humiliate them, and do not keep them away from their wives on campaign for too long and thus expose them to temptation. Do not withhold from them their due rights and cause them to rebel; and do not make them camp in an area with a lot of trees, because that will cause them to be scattered.

It was narrated that ‘Abul-`Ajfa` as-Sulami said: I heard ‘Umar say: Do not make women`s dowries expensive,... and he mentioned the same hadeeth.
