Musnad Ahmad

Farukh says that one day, during his caliphate, Sayyiduna Umar (may Allah be pleased with him) left his house to go to the mosque. On the way, he saw grain in several places. He asked: "What kind of grain is this?" People informed him that it had been imported. He said: "May Allah bless it and also bless the person who imported it." People said: "O Commander of the Faithful! This is hoarded goods." He asked: "Who has hoarded it?" People informed him that it was Farukh, the slave of Sayyiduna Uthman (may Allah be pleased with him), and another of your slaves. Sayyiduna Umar (may Allah be pleased with him) summoned both of them and said: "Why have you hoarded the food supplies of the Muslims?" They replied: "O Commander of the Faithful! We buy and sell with our own money (therefore, we have authority over what we own, and can sell it whenever we wish)." He said: "I heard the Messenger of Allah (peace and blessings be upon him) say: 'Whoever hoards the food supplies of the Muslims, Allah will afflict him with poverty and leprosy.'" Upon hearing this, Farukh immediately said: "O Commander of the Faithful! I promise Allah and you that I will not do this again." But the slave of Sayyiduna Umar (may Allah be pleased with him) insisted on his point, saying: "We buy and sell with our own money (therefore, we should have the right)." Abu Yahya says that later, when I saw him, he had been afflicted with leprosy.
