Abidah al-Salmani (may Allah have mercy on him) said that Sayyiduna Umar (may Allah be pleased with him) said: How much should a man be given so that it suffices him? I said: Such and such. He said: If I remain alive, I will set four thousand to give a man: a thousand for his weapons, a thousand for his expenses, a thousand for his family whom he leaves behind, and a thousand for his horse.
