Hadith 7.55

7.55:
Narrated `Abdullah bin `Umar : `Umar bin Al−Khattab said,
"When Hafsa bint `Umar became a widow after the death of (her
husband) Khunais bin Hudhafa As−Sahmi who had been one of the
companions of the Prophet, and he died at Medina. I went to
`Uthman bin `Affan and presented Hafsa (for marriage) to him.
He said, "I will think it over.' I waited for a few days, then
he met me and said, 'It seems that it is not possible for me
to marry at present.' " `Umar further said, "I met Abu Bakr
As−Siddique and said to him, 'If you wish, I will marry my
daughter Hafsa to you." Abu Bakr kept quiet and did not say
anything to me in reply. I became more angry with him than
with `Uthman. I waited for a few days and then Allah's Apostle
asked for her hand, and I gave her in marriage to him.
Afterwards I met Abu Bakr who said, 'Perhaps you became angry
with me when you presented Hafsa to me and I did not give you
a reply?' I said, 'Yes.' Abu Bakr said, 'Nothing stopped me to
respond to your offer except that I knew that Allah's Apostle
had mentioned her, and I never wanted to let out the secret of
Allah's Apostle. And if Allah's Apostle had refused her, I
would have accepted her.' "
