Hadith: 'A man will be brought on the Day of Resurrection and thrown into Hellfire, and his intestines will slip out and he will go around by them like a donkey goes around a millstone

عَنْ أُسَامَةَ بْنِ زَيْدٍ رضي الله عنه قَالَ: قِيلَ لَهُ: أَلَا تَدْخُلُ عَلَى عُثْمَانَ فَتُكَلِّمَهُ؟ فَقَالَ: أَتَرَوْنَ أَنِّي لَا أُكَلِّمُهُ إِلَّا أُسْمِعُكُمْ؟ وَاللهِ لَقَدْ كَلَّمْتُهُ فِيمَا بَيْنِي وَبَيْنَهُ، مَا دُونَ أَنْ أَفْتَتِحَ أَمْرًا لَا أُحِبُّ أَنْ أَكُونَ أَوَّلَ مَنْ فَتَحَهُ، وَلَا أَقُولُ لِأَحَدٍ يَكُونُ عَلَيَّ أَمِيرًا: إِنَّهُ خَيْرُ النَّاسِ بَعْدَمَا سَمِعْتُ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ:
«يُؤْتَى بِالرَّجُلِ يَوْمَ الْقِيَامَةِ، فَيُلْقَى فِي النَّارِ، فَتَنْدَلِقُ أَقْتَابُ بَطْنِهِ، فَيَدُورُ بِهَا كَمَا يَدُورُ الْحِمَارُ بِالرَّحَى، فَيَجْتَمِعُ إِلَيْهِ أَهْلُ النَّارِ، فَيَقُولُونَ: يَا فُلَانُ مَا لَكَ؟ أَلَمْ تَكُنْ تَأْمُرُ بِالْمَعْرُوفِ، وَتَنْهَى عَنِ الْمُنْكَرِ؟ فَيَقُولُ: بَلَى، قَدْ كُنْتُ آمُرُ بِالْمَعْرُوفِ وَلَا آتِيهِ، وَأَنْهَى عَنِ الْمُنْكَرِ وَآتِيهِ».
[صحيح] - [متفق عليه] - [صحيح مسلم: 2989]

Osāmah ibn Zayd (may Allah be pleased with him) reported that it was said to him: "Why do you not visit ‘Uthmān and talk to him?" He replied: "Do you think that I do not talk to him except that I make you hear? By Allah, I talked to him privately, without beginning something I do not like to be the first to begin; and I do not say to my ruler "You are the best among people" after I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say:
'A man will be brought on the Day of Resurrection and thrown into Hellfire, and his intestines will slip out and he will go around by them like a donkey goes around a millstone. The dwellers of Hellfire will gather around him and say: 'So-and-so, what is the matter with you? Did you not use to command us to do right and forbid us from doing wrong?' He will reply: 'Yes, I used to command what is right, but I would not do it myself, and I used to forbid doing what is wrong, but I fall into it myself''"
[Authentic hadith] - [Narrated by Bukhari & Muslim] - [Sahih Muslim - 2989]

Explanation

It was said to Osāmah ibn Zayd (may Allah be pleased with him): Why do you not go to ‘Uthmān ibn Affān (may Allah be pleased with him) and speak to him about the strife that has occurred among the people and the effort to put a complete end to it? He informed them that he spoke to him secretly, seeking the best interest, not inciting strife; that was because he did not want to openly denounce the rulers in public, lest it may be a reason for offense towards the Caliph - a door to strife and evil I will not be the first to open.
Then, Osāmah (may Allah be pleased with him) said that he advised the rulers in secret and did not flatter anyone, even if he was a ruler, and did not flatter them by praising them to their faces falsely. This was after he heard the Prophet (may Allah's peace and blessings be upon him) say that a man will be brought on the Day of Resurrection and thrown into Hellfire, and his intestines will come out of his stomach quickly due to the intense heat and severe torment. He will go around his intestines in this state in Hellfire like a donkey goes around its millstone. The people of Hellfire will gather around him in the form of a circle surrounding him, and they will ask him: O so-and-so, did you not use to command what is right and forbid what is wrong?!
He will say: I used to command what is right, but I would not do it, and I used to forbid what is wrong, but I would do it.
