وَعَن عُرْوَة بن أبي الْجَعْد الْبَارِقي
أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَعْطَاهُ دِينَارًا لِيَشْتَرِيَ بِهِ شَاةً فَاشْتَرَى لَهُ شَاتين فَبَاعَ إِحْدَاهمَا بِدِينَار وَأَتَاهُ بِشَاة ودينار فَدَعَا لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي بَيْعِهِ بِالْبَرَكَةِ فَكَانَ لَوِ اشْتَرَى تُرَابا لربح فِيهِ
Urwa ibn Abul Jad al-Bariqi said that God’s Messenger gave him a dinar to buy a sheep for him. He bought two sheep for him, sold one of them for a dinar and brought him a sheep and dinar. So God’s Messenger invoked a blessing on him in his business dealings, and he was such that if he had bought dust he would have made a profit from it.
