حَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، حَدَّثَنَا هُشَيْمٌ، حَدَّثَنَا يَعْلَى بْنُ عَطَاءٍ، حَدَّثَنَا عُمَارَةُ بْنُ حَدِيدٍ، عَنْ صَخْرٍ الْغَامِدِيِّ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ اللَّهُمَّ بَارِكْ لأُمَّتِي فِي بُكُورِهَا ‏"‏ ‏.‏ وَكَانَ إِذَا بَعَثَ سَرِيَّةً أَوْ جَيْشًا بَعَثَهُمْ فِي أَوَّلِ النَّهَارِ ‏.‏ وَكَانَ صَخْرٌ رَجُلاً تَاجِرًا وَكَانَ يَبْعَثُ تِجَارَتَهُ مِنْ أَوَّلِ النَّهَارِ فَأَثْرَى وَكَثُرَ مَالُهُ ‏.‏ قَالَ أَبُو دَاوُدَ وَهُوَ صَخْرُ بْنُ وَدَاعَةَ ‏.‏

Narrated Sakhr al-Ghamidi: The Prophet (PBUH) said: "O Allah, bless my people in their early mornings." When he sent out a detachment or an army, he sent them at the beginning of the day. Sakhr was a merchant, and he would send off his merchandise at the beginning of the day; and he became rich and had much wealth. Abu Dawud said: He is Sakhr b. Wada'ah. Translation Not Available
