After his conversion to Islam, Uthman was married by the Holy Prophet to his second daughter Ruqayya. Uthman migrated with Ruqayya to Abyssinia. He returned from Abyssinia and then migrated with his wife to Yathrib in 622. In Yathrib renamed Madina, Uthman carried on his business as a merchant. His business flourished, and Uthman and Ruqayya lived on happily for sometime in Madina. Such happiness was however short-lived. In 624 C.E. Ruqayya fell ill and died when the Holy Prophet and the Muslims were fighting with the Quraish at the battlefield of Badr. The news of the Muslim victory of Badr was received at Madina when the good lady was being buried. The Holy Prophet could not attend the funeral of Ruqayya.
Hafsa was the daughter of Umar. She was married to Khunays. Khunays was wounded in the battle of Uhud. The wounds proved fatal and he died soon after. Hafsa became a widow at a young age, and Umar felt much worried about her marriage.
After the death of Ruqayya, Uthman felt much distressed and disconsolate. Umar saw Uthman and dropped hints for offering Hafsa to him in marriage. Uthman did not respond favorably to the proposal. He said that after the death of Ruqayya he was too upset to think of another marriage.
Umar saw the Holy Prophet, and complained against the conduct of Uthman. The Holy Prophet consoled Umar and said,"Umar, do not worry. Hafsa would get a better husband than Uthman, and Uthman would get a better wife than Hafsa".
