That the Prophet ﷺ gave him one Dinar so as to buy a sheep for him. ʿUrwa bought two sheep for him with the money. Then he sold one of the sheep for one Dinar, and brought one Dinar and a sheep to the Prophet. On that, the Prophet ﷺ invoked Allah to bless him in his deals. So ʿUrwa used to gain (from any deal) even if he bought dust. (In another narration) ʿUrwa said, "I heard Messenger of Allah ﷺ saying, "There is always goodness in horses till the Day of Resurrection." (The subnarrator added, "I saw 70 horses in ʿUrwa's house.') (Sufyan said, "The Prophet ﷺ asked ʿUrwa to buy a sheep for him as a sacrifice.") (Using translation from Bukhārī 3642)   

أَنَّ النَّبِيَّ ﷺ أَعْطَاهُ دِينَارًا لِيَشْتَرِيَ لَهُ بِهِ شَاةً فَاشْتَرَى لَهُ بِهِ شَاتَيْنِ فَبَاعَ إِحْدَاهُمَا بِدِينَارٍ فَجَاءَهُ بِدِينَارٍ وَشَاةٍ فَدَعَا لَهُ بِالْبَرَكَةِ فِي بَيْعِهِ وَكَانَ لَوِ اشْتَرَى التُّرَابَ لَرَبِحَ فِيهِ قَالَ سُفْيَانُ كَانَ الْحَسَنُ بْنُ عُمَارَةَ جَاءَنَا بِهَذَا الْحَدِيثِ عَنْهُ قَالَ سَمِعَهُ شَبِيبُ مِنْ عُرْوَةَ فَأَتَيْتُهُ فَقَالَ شَبِيبٌ إِنِّي لَمْ أَسْمَعْهُ مِنْ عُرْوَةَ سَمِعْتُ الْحِيَّ يُخْبِرُونَهُ عَنْهُ وَلَكِنْ سَمِعْتُهُ يَقُولُ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ الْخَيْرُ مَعْقُودٌ بِنَوَاصِي الْخَيْلِ إِلَى يَوْمِ الْقِيَامَةِ قَالَ وَقَدْ رَأَيْتُ فِي دَارِهِ سَبْعِينَ فَرَسًا قَالَ سُفْيَانُ يَشْتَرِي لَهُ شَاةً كَأَنَّهَا أُضْحِيَّةٌ
