Someone said to him, "Why don't you go in to Uthman and speak with him?"He replied, "Do you think that I do not speak to him unless I let you hear it? By Allah, I have indeed spoken to him privately, between him and me, without opening a matter that I do not wish to be the first to open. I will not say of any man who becomes a ruler over me that he is the best of people, after I heard the Messenger of Allah ﷺ say, 'On the Day of Resurrection, a man will be brought and cast into the Fire. His intestines will spill out, and he will go around with them as a donkey goes around a millstone. The people of the Fire will gather around him and say, "So-and-so, what is wrong with you? Did you not used to enjoin good and forbid evil?" He will reply, "Yes, I used to enjoin good but not do it, and forbid evil but do it myself."'"
قيل له: ألا تدخل على عثمان فتكلمه؟ فقال: أترون أني لا أكلمه إلا أسمعكم؟ والله لقد كلمته فيما بيني وبينه، ما دون أن أفتتح أمرا لا أحب أن أكون أول من فتحه، ولا أقول لأحد، يكون علي أميرا: إنه خير الناس بعد ما سمعت رسول الله ﷺ يقول: يؤتى بالرجل يوم القيامة، فيلقى في النار، فتندلق أقتاب بطنه، فيدور بها كما يدور الحمار بالرحى، فيجتمع إليه أهل النار، فيقولون: يا فلان ما لك؟ ألم تكن تأمر بالمعروف، وتنهى عن المنكر؟ فيقول: بلى، قد كنت آمر بالمعروف ولا آتيه، وأنهى عن المنكر وآتيه.
Bukhari narrated it in the Book of Tribulations (7098), and Muslim narrated it in the Book of Asceticism (2989), both through Sulayman Amash, who said, I heard Abu Waail Shaqiq bin Salama say, It was said to Usama bin Zayd, "Won't you go in to see Uthman..." and he mentioned the rest of the hadith.
