他是在欧麦尔下葬后的第三个夜晚被宣誓效忠为哈里发的。据传，在那几天里，人们聚集在阿卜杜·拉赫曼·本·欧夫身边，向他提出建议，并与他私下交谈。凡是曾与他单独坐谈的、有见识的人，没有一个认为有谁能与奥斯曼相比。阿卜杜·拉赫曼坐下来接受效忠时，赞颂了真主，并在讲话中说：“我看到人们除了奥斯曼之外，不接受任何人。”伊本·阿萨基尔从穆斯瓦尔·本·玛赫拉马那里转述了此事。另一则传述中说：“阿里啊！我已在人们中间进行了考察，我看到他们没有人认为任何人能与奥斯曼相比。所以，你不要为自己开辟道路。”他握住奥斯曼的手说：“我们按照真主的遵行之道、祂的使者的遵行之道，以及在他之后的两位哈里发的遵行之道，向你宣誓效忠。”阿卜杜·拉赫曼向他宣誓效忠，迁士和辅士也都向他宣誓效忠。

He was pledged allegiance as khalifah three nights after the burial of cUmar. It is related that people got together, during those days, with cAbd ar-Rahman ibn cAwf, advising him and talking confidentially with him. Not one person of judgement who sat alone with him saw any to equal cUthman. When cAbd ar-Rahman sat to pledge allegiance, he praised Allah and said, during his speech, ‘I saw that people refuse anybody but cUthman.’ Ibn cAsakir narrated it from al-Miswar ibn Makhramah. In another narration, ‘Now! cAli, I have researched among people and I don’t see them regarding anyone equal to cUthman. Therefore, do not make a way against yourself.’ He took the hand of cUthman and said, ‘We pledge allegiance to you according to the Sunnah of Allah, the Sunnah of His Messenger and the Sunnah of the two khalifahs after him.’ cAbd ar-Rahman pledged allegiance to him and the Muhajirun and the Ansar pledged allegiance to him.

伊本·萨阿德传述，阿纳斯说：欧麦尔在去世前一小时派人召来艾布·塔勒哈·安萨里，说：“你要与这一群人，即协商者的同伴，以及五十名安солуза（安索尔）一同前往。我认为他们会聚集在某座房子里。你与你的同伴站在那扇门前，不许任何人进入，也不要让他们离开，不要让第三天过去，除非他们从自己人中推举出一位来主持事务。” 艾哈迈德的《圣训集》（《穆斯奈德》）中记载，艾布·瓦伊勒说：我问阿卜杜·拉赫曼·本·欧夫：“你怎么会向奥斯曼效忠，却忽略了阿里？”他说：“我的过错在哪里？我先去找阿里，对他说：‘我是否可以按照安拉的经典、祂使者的逊奈，以及艾布·伯克尔和欧麦尔的做法向你效忠？’他说：‘在我力所能及的范围内。’然后我又向奥斯曼提出同样的要求，他说：‘是的。’” 据传，阿卜杜·拉赫曼私下对奥斯曼说：“如果我不向你效忠，你会向我推荐谁？”他说：“阿里。”他又对阿里说：“如果我不向你效忠，你会向我推荐谁？”他说：“奥斯曼。”随后他召见祖拜尔，说：“如果我不向你效忠，你会向我推荐谁？”他说：“阿里或奥斯曼。”之后他又召见萨阿德，说：“你会向我推荐谁？”

Ibn Sacd narrated that Anas said: cUmar sent for Abu Talhah al- Ansari an hour before he died and said, ‘You be among fifty of the Ansar along with this group, the companions of the counsel, because they, as I believe, will gather in a house. Stand at that door with your companions, allow no-one to enter, and do not leave them to allow the third day to pass without their appointing one of themselves to the command.’ There is in the Musnad of Ahmad that Abu Wa’il said: I said to cAbd ar-Rahman ibn cAwf, ‘How could you have sworn allegiance to cUthman and neglected cAli?’ He said, ‘Where was my wrong action? I started with cAli and I said, “Shall I swear allegiance to you according to the Book of Allah, the Sunnah of His Messenger and the conduct of Abu Bakr and cUmar?” He said, “In what I am able.” I hen later I offered the same to cUthman and he said, “Yes.”’ It has been related that cAbd ar-Rahman said to cUthman in private, ‘If I don’t pledge allegiance to you who would you point out to me?’ He said, ‘cAli.’ He said to cAli, ‘If I don’t pledge allegiance to you who would you point out to me?’ He said, ‘cUthman.’ Then he called for az-Zubayr and said, ‘If I don’t pledge allegiance to you who would you point out to me?’ He said, ‘cAli or cUthman.’ Then later he called for Sacd and said, ‘Whom would you indicate to me?

“因为，至于我和你，我们都不想要它。”他说：“奥斯曼。”然后，阿卜杜·拉赫曼征询了所有显要人物的意见，发现他们大多数都倾向于奥斯曼。

because, as for me and you, we don’t want it.’ He said, ‘'Uthman.’ Then cAbd ar-Rahman sought the counsel of all the notables and saw that most of them were inclined to cUthman.

伊本·萨阿德和哈基姆传述：伊本·麦斯欧德愿安拉喜悦他，说：当人们向奥斯曼宣誓效忠时，他说：“我们已将指挥权交给了余下之人中最优秀的人，我们并未疏忽。” 在他哈里发任内的这一年，莱伊被攻克（归入伊斯兰统治），此前它曾被攻克，之后又失去。那一年，人们中有许多人流鼻血，以至于这一年被称为“流鼻血之年”。奥斯曼也深受鼻血之苦，以至于他未能参加朝觐，而是委派他人代替自己前往。那一年，许多拜占庭的堡垒被攻克。这一年，奥斯曼任命萨阿德·本·艾比·瓦卡斯为库法总督，并罢免了穆吉赫。

Ibn Sacd and al-Hakim narrated that Ibn Mascud, may Allah be pleased with him, said, when cUthman was pledged allegiance, ‘We have charged with command the best of those remaining and we have not been negligent.’ In this year of his khilafah, Rayy was opened [to Islam], and it had been opened previously and subsequently lost. In that year many nosebleeds occurred among people, so that it was known as, ‘The year of the nosebleeds.’ cUthman was afflicted by nosebleeds to such an extent that he stayed away from the Hajj and deputed someone in his place. In that year many Byzantine fortresses were taken. In it cUthman appointed Sacd ibn Abi Waqqas as governor of Kufa and removed al-Mughirah.

在公元25年（伊历），奥斯曼罢免了萨阿德在库发的职务，任命瓦利德·本·欧格白·本·艾比·穆艾特为总督。瓦利德是圣门弟子，也是奥斯曼同母异父的兄弟。这是人们对奥斯曼的第一件不满之事，因为他任用自己的亲属担任要职。有传说讲，瓦利德有一次醉酒后带领众人做晨礼，只念了四拜，礼毕后他转身对众人说：“我还要为你们多拜几拜吗？” 在公元26年（伊历），奥斯曼扩建并拓宽了禁寺（麦加大清真寺），并购买了毗邻的地块用于扩建。同年，萨布尔（或作沙布尔）被攻克。

In the year 25 AH, cUthman removed Sacd from Kufa and appointed al-Walid ibn cUqbah ibn Abi Mucayt — and he was a Companion, and a brother of cUthman on his mother’s side - and that was the first thing for which he was disliked; because he appointed his relatives to posts of authority. It has been told as a tale that al-Walid led them in prayer for the dawn prayer with four rakcfat when he was drunk, and that then he turned to them and said, ‘Shall I do more (raka?at) for you?’ In the year 26 AH, cUthman enlarged and extended al-Masjid al-Haram, and bought sites (adjoining it) for the enlargement. In the same year Sabur (possibly Shahpur) was opened.

在伊历27年，穆阿维叶率军远征塞浦路斯，率领军队渡海前往。阿ubada·本·萨米特与他们同行，他的妻子乌姆·哈勒姆·宾特·米勒汉·安萨里叶（属于安索尔）也随行。她从所骑的牲畜上跌落，在那里殉教而亡。先知ﷺ曾预言她将随这支军队出征，并为她祈祷，愿她能够在其中。她葬于塞浦路斯。同一年，阿尔贾占和达拉布吉尔被攻克。奥斯曼罢免了阿慕尔·本·阿绥在埃及的职务，任命阿卜杜拉·本·萨尔德·本·艾比·萨尔赫为埃及总督。他率军远征北非，并攻取了该地（归附伊斯兰），无论是平原还是山区。军中每人获得一千第纳尔，也有人说是三千第纳尔。随后，同一年，安达卢斯被攻克。

In the year 27 AH, Mucawiyah went on a military expedition to Cyprus, taking the armies by sea. cUbadah ibn as-Samit was with them and his wife, Umm Haram bint Milhan al-Ansariyah (of the Ansar). She fell from her riding beast, and died there as a martyr, and the Prophet, may Allah bless him and grant him peace, had foretold this army for her. He had supplicated for her that she should be of them. She was buried in Cyprus. In that same year Arrajan and Darabjird were opened. cUthman removed cAmr ibn al-cAs from Egypt and appointed cAbdullah ibn Sacd ibn Abi Sarh over it, who led an expedition against northern Africa and opened it [to Islam], both on the plains and in the mountains, and every man in the army received one thousand dinars, and it has also been said, three thousand dinars. Then Andalusia was opened in this same year.
