Musannaf Ibn Abi Shaybah 37707 — The words of Ibrahim al-Taymi

Ibrahim al-Taymi narrates from his father: My father went to Basrah and bought slaves for four thousand. They built his house for him, and then he sold them at a profit of four thousand. I said to him: O my father, if you were to go to Basrah and trade in slaves, you would make a good profit. He said: Do not say such a thing to me. By Allah, I felt no joy on obtaining this profit, nor has any desire arisen in my heart to obtain more profit of this kind.
