Narrated Urwah ibn AbulJa'd al-Bariqi:

The Prophet ﷺ gave him a dinar to buy a sacrificial animal or a sheep. He bought two sheep, sold one of them for a dinar, and brought him a sheep and dinar. So he invoked a blessing on him in his business dealing, and he was such that if had he bought dust he would have made a profit from it.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنْ شَبِيبِ بْنِ غَرْقَدَةَ، حَدَّثَنِي الْحَىُّ، عَنْ عُرْوَةَ، - يَعْنِي ابْنَ أَبِي الْجَعْدِ الْبَارِقِيِّ - قَالَ أَعْطَاهُ النَّبِيُّ ﷺ دِينَارًا يَشْتَرِي بِهِ أُضْحِيَةً أَوْ شَاةً فَاشْتَرَى شَاتَيْنِ فَبَاعَ إِحْدَاهُمَا بِدِينَارٍ فَأَتَاهُ بِشَاةٍ وَدِينَارٍ فَدَعَا لَهُ بِالْبَرَكَةِ فِي بَيْعِهِ فَكَانَ لَوِ اشْتَرَى تُرَابًا لَرَبِحَ فِيهِ .
