It was narrated from 'Urwah Al-Bariqi that :
the Prophet ﷺ gave him a Dinar to buy him a sheep, and he bought two sheep for him, then he sold one of them for a Dinar, and bought a Dinar and a sheep to the Prophet ﷺ. The Messenger of Allah ﷺ prayed for blessing for him.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ شَبِيبِ بْنِ غَرْقَدَةَ، عَنْ عُرْوَةَ الْبَارِقِيِّ، أَنَّ النَّبِيَّ ﷺ أَعْطَاهُ دِينَارًا يَشْتَرِي لَهُ شَاةً فَاشْتَرَى لَهُ شَاتَيْنِ فَبَاعَ إِحْدَاهُمَا بِدِينَارٍ فَأَتَى النَّبِيَّ ﷺ بِدِينَارٍ وَشَاةٍ فَدَعَا لَهُ رَسُولُ اللَّهِ ﷺ بِالْبَرَكَةِ . قَالَ فَكَانَ لَوِ اشْتَرَى التُّرَابَ لَرَبِحَ فِيهِ .
