`Uthman ibn `Affan ibn Abi al-`As ibn Umayya ibn `Abd Shams, Abu `Amr, Abu `Abd Allah, Abu Layla al-Qurashi al-Umawi (d. 35), the Prophet’s Friend, Amîr al-Mu’minîn, the third of the four Rightly-Guided Successors of the Prophet and third of the Ten promised Paradise. He is named Dhu al-Nûrayn or "Possessing Two Lights," a reference to his marriage with two daughters of the Prophet, Ruqayya then Umm Kulthum. He is among those who emigrated twice: once to Abyssinia, and again to Madina. He gathered together the Qur’an which he had read in its entirety before the Prophet. During his tenure as Caliph, Armenia, Caucasia, Khurasan, Kirman, Sijistan, Cyprus, and much of North Africa were added to the dominions of Islam. He related 146 hadiths from the Prophet. Among the Companions who narrated from him in the Nine Books are Anas, Abu Hurayra, Jundub, `Abd Allah ibn al-Zubayr, `Abd Allah ibn `Abbas, `Abd Allah ibn `Umar.
A host of prominent Followers narrated from him, among them al-Zuhri, Ibn al-Musayyib, al-Dahhak, and `Alqama.
`Uthman was extremely wealthy and generous. When he heard the Prophet say: "Whoever equips the army of al-`Usra, Paradise is for him," he brought the Prophet a thousand gold dinars which he poured into his lap. The Prophet picked them up with his hand and said repeatedly: "Nothing shall harm `Uthman after what he did today." It is also narrated that equipped the army of al-`Usra with seven hundred ounces of gold, or seven hundred and fifty camels and fifty horses.
The Prophet said: "The most compassionate of my Community towards my Community is Abu Bakr; the staunchest in Allah’s Religion is `Umar; and the most truthful in his modesty is `Uthman." The pebbles were heard by Abu Dharr glorifying Allah in the hands of the Prophet, Abu Bakr, `Umar, and `Uthman. The
Prophet particularly praised `Uthman for his modesty and said: "Shall I not feel bashful before a man when even the angels feel bashful before him?"
He was humble and was seen at the time of his caliphate sleeping alone in the mosque, wrapped in a blanket with no one around him, and riding on a mule with his son Na’il behind him.
It is related through several sound chains that `Uthman recited the Qur’an in a single rak`a. Ibrahim ibn Rustum al-Marwazi said: "Four are the Imams that recited the entire Qur’an in a single rak`a: `Uthman ibn `Affan, Tamim al-Dari, Sa`id ibn Jubayr, and Abu Hanifa." Ibn al-Mubarak also narrated that `Uthman
used to fast all year round. `Ali ibn Abi Talib said: "`Uthman was one of those who were ‘mindful of their duty and [did] good works, and again [were] mindful of [their] duty, and [believed], and once again [were] mindful of their duty, and did right. Allah loves those who do good.’ (5:93)" Ibn `Umar said that `Uthman was meant by the verse "Is he who pays adoration in the watches of the night, prostrate and standing, bewaring of the Hereafter and hoping for the mercy of his Lord. . ." (39:9).
