Hafsah bint Umar became widowed after the death of Khunays, or Hudhayfah bin Hudhafah (Abdul-Razzaq was uncertain), who was one of the companions of the Prophet ﷺ and had been present at Badr. He died in Medina.Umar said, "I met Uthman bin Affan and offered Hafsah to him. I said, 'If you wish, I will marry Hafsah to you.' He said, 'I will think about it.' I waited a few nights, then he met me and said, 'I do not wish to marry at this time.'"Umar continued, "Then I met Abu Bakr and said, 'If you wish, I will marry Hafsah, daughter of Umar, to you.' But he gave me no reply at all, and I felt more upset with him than I had with Uthman. I waited a few nights, then the Messenger of Allah ﷺ proposed to her, and I married her to him.""Later, Abu Bakr
met me and said, 'Perhaps you were upset with me when you offered Hafsah to me and I gave you no reply?'I said, 'Yes.'He said, 'Nothing prevented me from giving you a reply when you offered her to me except that I had heard the Messenger of Allah ﷺ mention her, and I would not divulge the secret of the Messenger of Allah ﷺ. Had he left her, I would have married her.'"
حدثنا عبد الرزاق قال أخبرنا معمر عن الزهري عن سالم عن ابن عمر
تأيمت حفصة بنت عمر من خنيس أو حذيفة بن حذافة شك عبد الرزاق وكان من أصحاب النبي ﷺ ممن شهد بدرا فتوفي بالمدينة قال فلقيت عثمان بن عفان فعرضت عليه حفصة فقلت إن شئت أنكحتك حفصة قال سأنظر في ذلك فلبثت ليالي فلقيني فقال ما أريد أن أتزوج يومي هذا قال عمر فلقيت أبا بكر رضي الله عنه فقلت إن شئت أنكحتك حفصة ابنة عمر فلم يرجع إلي شيئا فكنت أوجد عليه مني على عثمان فلبثت ليالي فخطبها إلي رسول الله ﷺ فأنكحتها إياه فلقيني أبو بكر رضي الله عنه فقال لعلك وجدت علي حين عرضت علي حفصة فلم أرجع إليك شيئا قال قلت نعم قال فإنه لم يمنعني أن أرجع إليك شيئا حين عرضتها علي إلا أني سمعت رسول الله ﷺ يذكرها ولم أكن لأفشي سر رسول الله ﷺ ولو تركها لنكحتها
Its chain of transmission is sahih. Khunays bin Hudhafa, in the diminutive form, was a Qurashi from Banu Sahm. He was wounded on the day of Uhud and died from it. Abdul-Razzaq was uncertain whether his name was Khunays or Huzaifa, but the correct view, held without disagreement, is that it was Khunays.
