Musnad Ahmad

Malik bin Aws says that Sayyiduna Umar (may Allah be pleased with him) used to swear by three things. He used to say: By Allah! No one is more entitled to this wealth than another (rather, all are equally deserving), and I am not more entitled to it than anyone else. By Allah! Every Muslim has a right to this wealth except for the slave who is still owned by his master. However, we will assign ranks according to the Book of Allah and will adopt the method of distribution from the Prophet (peace and blessings be upon him). Thus, there is a man who endured great trials for the sake of Islam, a man who is an early convert to Islam, a man who remained in Islam, and a man who remained in need. By Allah! If I live, it will surely happen that a shepherd will come from Mount Sana'a and will take his share from this wealth, and his animals will continue to graze in their place.
