Sahih Bukhari | Volume 7 | Hadith Number 60
Narrated by 'Abdullah bin 'Umar
When Hafsa, 'Umar's daughter became a widow because of the death of her (husband) Ibn Hudhafa As-Sahmi who was one of the companion of the Prophet and the one of the Badr warriors and died at Medina, 'Umar said, "I met 'Uthman bin 'Affan and gave him an offer, saying, 'If you wish, I will marry Hafsa to you.' He said. 'I will think it over' I waited for a few days, then he met me and said, 'I have made up my mind not to marry at present' "Umar added, "Then I met Abu Bakr and said to him, 'If you wish, I will marry Hafsa to you.'"
