Sunan Abi Dawud, Hadith 3378 ⓘ

Narrated Urwah ibn AbulJa'd al-Bariqi: The Prophet 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 صلى الله عليه وسلم 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 ‏.‏
