In the name of Allah, all praise is to him, The One. I send peace and blessings upon His messenger, Al-Mustafa, upon his family, companions and those who followed him in goodness until The Day of Judgement (Youm Al-Qiyaamah). To proceed:
Usamah bin Zaid (radiAllahu ‘anhu–may Allah be pleased with them) reported: Messenger of Allah ﷺ said, “A man will be brought on the Day of Resurrection and will be cast into Hell; his intestines will pour forth and he will go round them as a donkey goes round a millstone. The inmates of Hell will gather round him and say: ‘What has happened to you, O so-and-so? Were you not enjoining us to do good and forbidding us to do evil?’ He will reply: ‘I was enjoining you to do good, but was not doing it myself; and I was forbidding you to do evil, but was doing it myself’”. [Al-Bukhari and Muslim]
This Hadeeth is a great warning for the man who enjoins with good but doesn’t do it himself and prohibits from evil but does it. And I seek refuge in Allah!
He said, “A man will be brought on the Day of Resurrection”, meaning the angels will bring him and throw him into the Hellfire. They wont enter him softly; rather, he will be thrown in as a rock is thrown into a river; consequently causing his intestines to pour forth. I seek refuge in Allah!
“And he will go round them as a donkey goes round a millstone” This is a despicable comparison. A description of it: as in old mills before they had modern machinery. They used to grind two stones together, inside the upper one the would be a hole allowing grain to enter. And inside this whole would be a piece of wood, which a donkey would have tied to it’s back; turning the millstone, grinding that what is in it.
So, the people of the Hellfire with gather around him asking him, “Whats with you?” i.e. what caused you to be here and you command with good and prohibit with evil? And he will reply, ”I was enjoining you to do good, but was not doing it myself”. Commanding the people, “Pray,” and you didn’t pray; “Give Zakat on your wealth,” and you didn’t give Zakat; “Be good to your parents,” and weren’t good to your parents. Therefore, this is how you command with good but not do it yourself.
“And I was forbidding you to do evil, but was doing it myself.” He said to the people, “Don’t slander!”, “Don’t deal in interest!”, “Don’t cheat in business!”, “Don’t be corrupt in your dealings!”, “Don’t bad to your neighbors!”, and what resembles that. But he did them himself (I seek refuge in Allah): buying with interest, cheating, corrupt in dealings, and bad to your neighbors and other than them. So with that, he commanded with good and didn’t do it himself, and prohibited from evil and did it (we ask Allah for wellness); therefore, he will be punished with this punishment and shamed with this shame.
Thus, it is obligatory upon a person to start with himself; commanding himself with good and prohibiting himself from evil. Surely, the person with the most right on you after the Messenger of Allah ﷺ is yourself. Start with yourself then try to advice your brothers; commanding them with good and prohibiting them from evil, so you will be righteous and making others righteous.
We ask Allah to make me and you from the righteous people who make others righteous. Verily he is honorable and noble!
