It is narrated from Sawadah bin Ziyad (may Allah have mercy on him) that Sayyiduna Umar bin Abdul Aziz (may Allah have mercy on him) wrote to Abdul Hameed bin Abdur Rahman: "Indeed, two shares for the horseman and one share for the foot soldier are from the obligatory division prescribed by the Messenger of Allah (peace and blessings be upon him), and by my life, this is an issue in which I do not know of any Muslim who intended to reduce it. So whoever intends such a thing, punish him. And peace be upon you."
