Humran narrates that once Sayyiduna Uthman (may Allah be pleased with him) was sitting at the door of the mosque. I saw that he asked for water, first washed his hands, then washed his face three times, rinsed his mouth and put water into his nose, washed his arms including the elbows three times, then wiped his head and passed both hands over the outer surface of his ears, then passed his hands over his beard, and washed his feet including the ankles three times. Then he stood up and prayed two rak‘ahs and said: I have shown you how the Prophet (peace and blessings be upon him) performed ablution, just as I saw him do it, and I have also shown you how he prayed two rak‘ahs, just as he did. And after completing these two rak‘ahs, the Messenger of Allah (peace and blessings be upon him) said: Whoever performs ablution like this of mine and then prays two rak‘ahs in such a way that he does not let any thoughts or distractions enter his heart, Allah Almighty will forgive all his past sins.

Shaqiq (may Allah have mercy on him) says that once Walid bin Uqbah met Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him). Walid said: "What is the matter, you are not being just with the Commander of the Faithful, Sayyiduna Uthman (may Allah be pleased with him)?" He replied: "Convey this message from me to him: I did not flee on the day of the Battle of Uhud, I was not absent from the Battle of Badr, nor did I abandon the Sunnah of Sayyiduna Umar (may Allah be pleased with him)." Walid went and conveyed all this to Sayyiduna Uthman (may Allah be pleased with him). He said: "As for what Abdur Rahman (may Allah be pleased with him) said, that I did not flee from the Battle of Uhud, how can he reproach me for a slip which Allah Himself has forgiven? Thus, the command of Allah, the Exalted, is: 'Those of you who turned their backs on the day the two armies met, it was Satan who caused them to slip because of some of what they had earned.' And as for the reproach that I was absent from the Battle of Badr, the real matter is that I was occupied in caring for the daughter of the Prophet (peace and blessings be upon him) and my wife, Sayyida Ruqayyah (may Allah be pleased with her), until she passed away during that time. Meanwhile, the Prophet (peace and blessings be upon him) included my share in the spoils of Badr with the participants, and it was considered that whoever the Prophet (peace and blessings be upon him) allotted a share to, was counted among the participants of Badr. As for his statement that I did not abandon the Sunnah of Sayyiduna Umar (may Allah be pleased with him), the truth is that neither I nor he have the strength for that. Go and convey these things to him."

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 performs the ‘Isha prayer in congregation, it is as if he has stood in prayer for half the night, and whoever also performs the Fajr prayer in congregation, it is as if he has stood in prayer for the entire night.

Nabiyah bin Wahb says that Ibn Muammar planned to marry his son to the daughter of Shaibah bin Jubair during Hajj, and he sent me to Aban bin Uthman, may Allah have mercy on him, who was the Amir of Hajj. I went to him and said, "Your brother wants to marry his son and wishes for you to participate in it." He said, "I did not consider him to be an Iraqi villager. Remember! A person in the state of Ihram cannot marry nor arrange the marriage of anyone else." Then he narrated a hadith on this subject from Sayyiduna Uthman, may Allah be pleased with him.

Humran reports that Sayyiduna Uthman (may Allah be pleased with him) sat on a bench and performed ablution, washing each limb three times, and said: I heard the Prophet (peace and blessings be upon him) say: "Whoever performs ablution like mine, then offers prayer, his sins fall away from his face, hands, feet, and head."

Nabiyah bin Wahb says that when Umar bin Ubaidullah’s eyes started hurting, he asked Aban bin Uthman about this issue—what should he do? He replied by sending word that he could apply antimony (surma) of aloe (sabr), (he should be patient and not apply surma until he comes out of ihram), because I heard Sayyiduna Uthman (may Allah be pleased with him) narrate such a hadith from the Prophet (peace and blessings be upon him).

Aban bin Uthman, may Allah have mercy on him, saw a funeral and stood up, and said that once Sayyiduna Uthman, may Allah be pleased with him, saw a funeral and he also stood up, and he said that once the Prophet, peace and blessings be upon him, saw a funeral and he also stood up.

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 in the state of ihram should neither marry himself nor send a marriage proposal to anyone."

It is narrated from Sayyiduna Uthman (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said regarding the Muhrim: If his eyes begin to ache, he should apply antimony of sabr.

It is narrated from Sayyiduna Uthman (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever dies in such a state that he is certain that there is no deity except Allah, he will enter Paradise."
