Salim bin Abi Al-Ja'd (may Allah have mercy on him) says that once Sayyiduna Uthman (may Allah be pleased with him) called some of the noble Companions (may Allah be pleased with them), among whom was Sayyiduna Ammar bin Yasir (may Allah be pleased with him), and said: "I want to ask you some questions and have you confirm a few things. I ask you by Allah, do you not know that the Prophet (peace and blessings be upon him) used to give preference to the Quraysh over other people, and to Banu Hashim over all of Quraysh?" The people remained silent. Sayyiduna Uthman (may Allah be pleased with him) said: "If the keys to Paradise were in my hand, I would give them to Banu Umayyah so that all of them could enter Paradise." (Having kinship ties is a natural thing; this was actually an answer to the question people used to raise against Sayyiduna Uthman (may Allah be pleased with him) regarding favoritism towards relatives.) After this, he addressed Sayyiduna Talhah (may Allah be pleased with him) and Sayyiduna Zubair (may Allah be pleased with him) and said: "Shall I tell you something about him, i.e., Sayyiduna Ammar (may Allah be pleased with him)? I was once walking, holding the hand of the Prophet (peace and blessings be upon him), until we reached the valley of Batha, and the Prophet (peace and blessings be upon him) came to his parents, where they were being subjected to various punishments. Ammar's father, upon seeing the Prophet (peace and blessings be upon him), said: 'O Messenger of Allah! Will we always remain like this?' The Prophet (peace and blessings be upon him) said: 'Be patient,' then he supplicated: 'O Allah! Forgive the family of Yasir.' I too am now being patient."

It is narrated from Sayyiduna Uthman (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "A person has no right to anything except the shade of a house, pieces of dry bread, clothing sufficient to cover the private parts, and water."

Once, a man saw Sayyiduna Uthman (may Allah be pleased with him) sitting near the second gate of the mosque. He ordered the meat of the shoulder and began to eat the meat off the bone. Then, standing just like that, he performed the prayer without renewing his ablution, and said: I sat as the Prophet (peace and blessings be upon him) sat, I ate what the Prophet (peace and blessings be upon him) ate, and I did what the Prophet (peace and blessings be upon him) did.

Once during the days of Hajj, Sayyiduna Uthman (may Allah be pleased with him) said in the plain of Mina: O people! I will narrate to you a hadith which I heard from the Prophet (peace and blessings be upon him): Guarding for one day in the way of Allah is better than a thousand days in ordinary circumstances. Therefore, whoever wishes, let him take part in it as he wills. After saying this, he said: Have I conveyed the message? The people said: Yes! He said: O Allah, bear witness.

Once during the days of Hajj, Sayyiduna Uthman (may Allah be pleased with him) led the people in Mina in four complete rak'ahs instead of shortening the prayer. The people were astonished at this. Sayyiduna Uthman (may Allah be pleased with him) said: "O people! I have become a resident after coming to Makkah Mukarramah, and I heard the Prophet (peace and blessings be upon him) say that whoever becomes a resident in a city will pray the prayer of a resident."

Saeed bin Musayyib (may Allah have mercy on him) says that I heard Sayyiduna Uthman (may Allah be pleased with him) delivering a sermon on the pulpit, saying: I used to buy dates from a Jewish family and tribe called Banu Qaynuqa, and after keeping my profit, I would sell them further. When the Prophet (peace and blessings be upon him) came to know of this, he said: "Uthman! When you buy, weigh it, and when you sell, sell it by weighing."

The previous hadith is also narrated through this second chain of transmission.

It is narrated from Sayyiduna Uthman (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever recites this supplication, nothing will be able to harm him «بسم الله الذى لا يضر مع اسمه شيء فى الارض ولا فى السماء وهو السميع العليم» .

It is narrated from Sayyiduna Uthman (may Allah be pleased with him) that I heard the Messenger of Allah (peace and blessings be upon him) say once: "I know a word that if any servant says it, believing in it with his heart as truth, the fire of Hell will become forbidden for him." Sayyiduna Umar (may Allah be pleased with him) said to him: "Shall I tell you what that word is?" That word is sincerity, which Allah made obligatory upon His Prophet and his companions (may Allah be pleased with them). This is the same word of piety that the Prophet (peace and blessings be upon him) repeatedly presented before his uncle Abu Talib at the time of his death, that is, the testimony of the oneness of Allah.

Sayyiduna Zaid bin Khalid al-Juhani (may Allah be pleased with him) once asked Sayyiduna Uthman (may Allah be pleased with him) that if a man has intercourse with his wife but does not ejaculate, what is the ruling? He replied that he should perform ablution as he does for prayer, and wash his private part, and said that he heard the Prophet (peace and blessings be upon him) say this. The narrator says that then I asked the same question to Sayyiduna Ali, Sayyiduna Zubair, Sayyiduna Talha, and Sayyiduna Ubayy bin Ka'b (may Allah be pleased with them), and they also gave the same answer.
