عَن صخْرِ بن وَداعةَ الغامِديِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «اللَّهُمَّ بَارِكْ لِأُمَّتِي فِي بُكُورِهَا» وَكَانَ إِذا بعثَ سريَّةً أوْ جَيْشًا بَعَثَهُمْ مِنْ أَوَّلِ النَّهَارِ وَكَانَ صَخْرٌ تَاجِرًا فَكَانَ يَبْعَثُ تِجَارَتَهُ أَوَّلَ النَّهَارِ فَأَثْرَى وَكَثُرَ مالُه. رَوَاهُ التِّرْمِذِيّ وَأَبُو دَاوُد والدارمي

Buraida told that while God’s Messenger was walking a man who had an ass came to him and, moving to the back of the animal, invited him to mount, but he said, “No; you have more right to ride in front on your animal unless you grant that right to me." The man replied that he did, and so he mounted. Tirmidhi and Abu Dawud transmitted it.
