Sahih al-Bukhari 3059

Ismaʿil narrated to us: He said: Malik told me, from Zayd ibn Aslam, from his father, that ʿUmar ibn al-Khattab (may Allah be pleased with him) appointed a freedman of his, named Hunayy, over the protected pasture. He said, “Hunayy, be considerate toward the Muslims and beware the supplication of the wronged, for the supplication of the wronged is answered. Admit the owner of a small herd of camels and the owner of a small flock of sheep. Keep away the livestock of Ibn ʿAwf and the livestock of Ibn ʿAffan, for if their livestock perish, they can return to their date palms and crops. But if the livestock of the owner of a small camel herd or the owner of a small sheep flock perish, he will come to me with his children and say, ‘Commander of the Believers!’ Would I then abandon them? May you be bereft of your father! Water and pasture are easier for me to provide than gold and silver. By Allah, they think that I have wronged them. This is their land; they fought for it in the pre-Islamic era and entered Islam while it was theirs. By Him in whose hand my soul is, were it not for the wealth I equip for use in Allah’s cause, I would not have reserved even a handspan of their land as protected pasture.”
