حَدَّثَنِي إِبْرَاهِيمُ بْنُ حَمْزَةَ حَدَّثَنَا حَاتِمٌ عَنْ عَبْدِ الرَّحْمَنِ بْنِ حُمَيْدٍ الزُّهْرِيِّ قَالَ سَمِعْتُ عُمَرَ بْنَ عَبْدِ الْعَزِيزِ يَسْأَلُ السَّائِبَ ابْنَ أُخْتِ الْنَّمِرِ مَا سَمِعْتَ فِي سُکْنَی مَکَّةَ قَالَ سَمِعْتُ الْعَلَائَ بْنَ الْحَضْرَمِيِّ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ ثَلَاثٌ لِلْمُهَاجِرِ بَعْدَ الصَّدَرِ
صحیح بخاری · Hadith 3934
Narrated Sahl bin Sa`d: The Prophet's companions did not take as a starting date for the Muslim calendar, the day, the Prophet had been sent as an Apostle or the day of his death, but the day of his arrival at Medina.
