Musannaf Ibn Abi Shaybah

Hazrat Ulay bin Rabah (may Allah have mercy on him) narrates that Hazrat Umar bin Khattab (may Allah be pleased with him) addressed the people at the place of Jabiyah: He (may Allah be pleased with him) praised and glorified Allah, then said: Whoever wishes to ask about the Qur'an should come to Hazrat Ubayy bin Ka'b (may Allah be pleased with him). And whoever wishes to ask about the shares of inheritance should come to Hazrat Zayd bin Thabit (may Allah be pleased with him). And whoever wishes to ask about jurisprudence should come to Hazrat Mu'adh bin Jabal (may Allah be pleased with him). And whoever wishes to ask about wealth should come to me. Indeed, Allah Almighty has made me the treasurer and distributor. Beware, I will begin first with the earliest Muhajireen. I and my companions will give them their grants. Then I will begin with the Ansar, who gave a place to faith and remained steadfast in faith. Thus, I and my companions will give them their grants. Then I will begin with the pure wives of the Noble Prophet (peace and blessings be upon him) and will give them their grants. And whoever hastened in migration, the grant will also hasten towards him. And whoever was slow in migration, the grant will also be slow for him. None among you will ever be blamed except at the place where his mount sits.
