Usama bin Zayd reported,

Someone said to him, "Will you not go in to Uthman and speak with him?"He replied, "Do you think that I do not speak to him unless you hear it? By Allah, I have spoken to him privately between him and me, without initiating a matter that I would not like to be the first to open. Nor will I say of anyone who is appointed as ruler over me, '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 has happened to you? Did you not used to enjoin what is right and forbid what is wrong?" He will reply, "Yes, I used to enjoin what is right but not do it, and forbid what is wrong but do it myself."'"

عن أسامة بن زيد، قال

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 بعدما 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.
