Urwa bin Abu Jaad Bariqi reported,

The Prophet ﷺ gave him a Dinar to buy him a sheep with it. He bought two sheep with it, then sold one of them for a Dinar and brought him a Dinar and a sheep. The Prophet ﷺ supplicated for blessing in his trade, and after that, even if he had bought dirt, he would have made a profit on it.

Sahih

عن عروة البارقي

أن النبي ﷺ أعطاه دينارا يشتري له به شاة، فاشترى له به شاتين، فباع إحداهما بدينار، وجاءه بدينار وشاة، فدعا له بالبركة في بيعه، وكان لو اشترى التراب لربح فيه.
