ʿUmar bin Al-Khattab said, "When (my daughter) Hafsa bint ʿUmar lost her husband Khunais bin Hudhaifa As-Sahrni who was one of the companions of Messenger of Allah ﷺ and had fought in the battle of Badr and had died in Medina, I met ʿUthman bin ʿAffan and suggested that he should marry Hafsa saying, "If you wish, I will marry Hafsa bint ʿUmar to you,' on that, he said, 'I will think it over.' I waited for a few days and then he said to me. 'I am of the opinion that I shall not marry at present.' Then I met Abu Bakr and said, 'if you wish, I will marry you, Hafsa bint ʿUmar.' He kept quiet and did not give me any reply and I became more angry with him than I was with ʿUthman . Some days later, Messenger of Allah ﷺ demanded her hand in marriage and I married her to him. Later on Abu Bakr met me and said, "Perhaps you were angry with me when you offered me Hafsa for marriage and I gave no reply to you?' I said, 'Yes.' Abu Bakr said, 'Nothing prevented me from accepting your offer except that I learnt that Messenger of Allah ﷺ had referred to the issue of Hafsa and I did not want to disclose the secret of Messenger of Allah ﷺ , but had he (i.e. the Prophet) given her up I would surely have accepted her."

أَنَّ عُمَرَ بْنَ الْخَطَّابِ حِينَ تَأَيَّمَتْ حَفْصَةُ بِنْتُ عُمَرَ مِنْ خُنَيْسِ بْنِ حُذَافَةَ السَّهْمِيِّ وَكَانَ مِنْ أَصْحَابِ رَسُولِ اللهِ ﷺ فَتُوُفِّيَ بِالْمَدِينَةِ فَقَالَ عُمَرُ فَأَتَيْتُ عُثْمَانَ بْنَ عَفَّانَ فَعَرَضْتُ عَلَيْهِ حَفْصَةَ بِنْتَ عُمَرَ قَالَ قُلْتُ إِنْ شِئْتَ أَنْكَحْتُكَ حَفْصَةَ قَالَ سَأَنْظُرُ فِي أَمْرِي فَلَبِثْتُ لَيَالِي ثُمَّ لَقِيَنِي فَقَالَ قَدْ بَدَا لِي أَنْ لَا أَتَزَوَّجَ يَوْمِي هَذَا قَالَ عُمَرُ فَلَقِيتُ أَبَا بَكْرٍ الصِّدِّيقَ فَقُلْتُ لَهُ إِنْ شِئْتَ زَوَّجْتُكَ حَفْصَةَ بِنْتَ عُمَرَ فَصَمَتَ أَبُو بَكْرٍ فَلَمْ يَرْجِعْ إِلَيَّ شَيْئًا فَكُنْتُ عَلَيْهِ أَوْجَدَ مِنِّي عَلَى عُثْمَانَ فَلَبِثْتُ لَيَالِيَ ثُمَّ خَطَبَهَا رَسُولُ اللهِ ﷺ فَأَنْكَحْتُهَا إِيَّاهُ فَلَقِيَنِي أَبُو بَكْرٍ فَقَالَ لَعَلَّكَ وَجَدْتَ عَلَيَّ حِينَ عَرَضْتَ عَلَيَّ حَفْصَةَ فَلَمْ أَرْجِعْ إِلَيْكَ شَيْئًا قَالَ عُمَرُ قُلْتُ نَعَمْ قَالَ فَإِنَّهُ لَمْ يَمْنَعْنِي أَنْ أَرْجِعَ إِلَيْكَ فِيمَا عَرَضْتَ عَلَيَّ إِلَّا أَنِّي قَدْ كُنْتُ عَلِمْتُ أَنَّ رَسُولَ اللهِ ﷺ «قَدْ ذَكَرَهَا فَلَمْ أَكُنْ لِأُفْشِيَ سِرَّ رَسُولِ اللهِ ﷺ وَلَوْ تَرَكَهَا رَسُولُ اللهِ ﷺ قَبِلْتُهَا»
