Musnad Ahmad 308
It was narrated that Abu Labeed said:
A man called Bairah bin Asad went out from Tahiyah, migrating [Hijrah], and he reached Madinah a few days after the Messenger of Allah (ﷺ) died ‘Umar (رضي الله عنه) saw him and realized he was a stranger, so he said to him. Who are you? Are you from Oman? He said: Yes. He took him by the hand and brought him to Abu Bakr (رضي الله عنه) and said: This man is from the land of which heard the Messenger of Allah (ﷺ) saying: `I know a land called Oman at the edge of the sea, in it is a tribe of the Arabs who, if my envoy goes to them, they will not shoot arrows or throw stones at him.”
حَدَّثَنَا يَزِيدُ، أَخْبَرَنَا جَرِيرٌ، أَنْبَأَنَا الزُّبَيْرُ بْنُ الْخِرِّيتِ، عَنْ أَبِي لَبِيدٍ، قَالَ خَرَجَ رَجُلٌ مِنْ طَاحِيَةَ مُهَاجِرًا يُقَالُ لَهُ بَيْرَحُ بْنُ أَسَدٍ فَقَدِمَ الْمَدِينَةَ بَعْدَ وَفَاةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِأَيَّامٍ فَرَآهُ عُمَرُ رَضِيَ اللَّهُ عَنْهُ فَعَلِمَ أَنَّهُ غَرِيبٌ فَقَالَ لَهُ مَنْ أَنْتَ قَالَ مِنْ أَهْلِ عُمَانَ قَالَ نَعَمْ قَالَ فَأَخَذَ بِيَدِهِ فَأَدْخَلَهُ عَلَى أَبِي بَكْرٍ رَضِيَ اللَّهُ عَنْهُ فَقَالَ هَذَا مِنْ أَهْلِ الْأَرْضِ الَّتِي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ إِنِّي لَأَعْلَمُ أَرْضًا يُقَالُ لَهَا عُمَانُ يَنْضَحُ بِنَاحِيَتِهَا الْبَحْرُ بِهَا حَيٌّ مِنْ الْعَرَبِ لَوْ أَتَاهُمْ رَسُولِي مَا رَمَوْهُ بِسَهْمٍ وَلَا حَجَرٍ ‏.‏
