حَدَّثَنَا بِشْرُ بْنُ شُعَيْبِ بْنِ أَبِي حَمْزَةَ، حَدَّثَنِي أَبِي، عَنِ الزُّهْرِيِّ، حَدَّثَنِي عُرْوَةُ بْنُ الزُّبَيْرِ، أَنَّ عُبَيْدَ اللَّهِ بْنَ عَدِيِّ بْنِ الْخِيَارِ، أَخْبَرَهُ أَنَّ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ قَالَ لَهُ إِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَهُ إِنَّ اللَّهَ قَدْ بَعَثَ مُحَمَّدًا عَلَيْهِ الصَّلَاة وَالسَّلَامُ بِالْحَقِّ فَكُنْتُ مِمَّنْ اسْتَجَابَ لِلَّهِ وَلِرَسُولِهِ وَآمَنَ بِمَا بَعَثَ بِهِ مُحَمَّدًا عَلَيْهِ الصَّلَاة وَالسَّلَامُ ثُمَّ هَاجَرْتُ الْهِجْرَتَيْنِ وَنِلْتُ صِهْرَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَبَايَعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَوَاللَّهِ مَا عَصَيْتُهُ وَلَا غَشَشْتُهُ حَتَّى تَوَفَّاهُ اللَّهُ عَزَّ وَجَلَّ.
English Translation
`Ubaidullah bin `Adiyy bin al-Khiyar narrated that `Uthman (رضي الله عنه) said to him:: Verily Allah, may He be glorified and exalted, sent Muhammad (ﷺ) with the truth and I was one of those who responded to (the call of) Allah and His Messenger, and I believed in that with which Muhammad (ﷺ) was sent. Then I migrated twice, and I also attained the honour of becoming the son-in-law of the Messenger of Allah (ﷺ); I swore allegiance to the Messenger of Allah (ﷺ), and by Allah, I never disobeyed him or betrayed him until Allah, may He be glorified and exalted, took his soul in death.
