Sunan Abi Dawud Commercial Transactions (Kitab Al-Buyu) al-Hasan bin al-Sbah al-Bzar الحسن بن الصباح البزار al-Zubair bin al-Kharrayt الزبير بن الخريت Sa'id bin Zayd Urwa bin al-Ja'd / Abi al-Ja'd Sahih 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. https://parallelquran.com/hadith/sunan-abi-dawud-3384/
