Silah bin Zufar narrated: A man from the tribe of Hamdan came to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) riding a piebald horse and said: "My paternal uncle has made me the executor of his estate, and this horse is part of his estate. Shall I buy it?" He said: "No, and do not borrow anything from their wealth."
