It was narrated from Sakhr Al-Ghamidi that the Messenger of Allah (ﷺ) said:
"O Allah, bless my nation in their early mornings (i.e., what they do early in the morning)." (Hasan)He said: "When he sent out a raiding party or an army, he would send them at the beginning of the day." He said: (1) "Sakhr was a man engaged in trade, and he used to send his goods out at the beginning of the day, and his wealth grew and increased."
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا هُشَيْمٌ، عَنْ يَعْلَى بْنِ عَطَاءٍ، عَنْ عُمَارَةَ بْنِ حَدِيدٍ، عَنْ صَخْرٍ الْغَامِدِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏ "‏ اللَّهُمَّ بَارِكْ لأُمَّتِي فِي بُكُورِهَا ‏"‏ ‏.‏ قَالَ وَكَانَ إِذَا بَعَثَ سَرِيَّةً أَوْ جَيْشًا بَعَثَهُمْ فِي أَوَّلِ النَّهَارِ ‏.‏ قَالَ وَكَانَ صَخْرٌ رَجُلاً تَاجِرًا فَكَانَ يَبْعَثُ تِجَارَتَهُ فِي أَوَّلِ النَّهَارِ فَأَثْرَى وَكَثُرَ مَالُهُ ‏.‏
