Narrated 'Urwa al-Bariqi (RA):

The Prophet (ﷺ) gave him a Dinar to buy a sacrificial animal or a sheep. He bought two sheep with it, sold one of them for a Dinar and came back to him with a goat and a Dinar. So he invoked blessings on him in his business dealings, and he was such that if he had bought soil (of the earth) he would have made profit from it. [Reported by al-Khamsah except an-Nasa'i].

وَعَنْ عُرْوَةَ الْبَارِقِيِّ ‏- رضى الله عنه ‏- { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-أَعْطَاهُ دِينَارًا يَشْتَرِي بِهِ أُضْحِيَّةً, أَوْ شَاةً, فَاشْتَرَى شَاتَيْنِ, فَبَاعَ إِحْدَاهُمَا بِدِينَارٍ, فَأَتَاهُ بِشَاةٍ وَدِينَارٍ, فَدَعَا لَهُ بِالْبَرَكَةِ فِي بَيْعِهِ, فَكَانَ لَوْ اِشْتَرَى تُرَابًا لَرَبِحَ فِيهِ } رَوَاهُ اَلْخَمْسَةُ إِلَّا النَّسَائِيَّ [1]‏ .‏
