Musannaf Ibn Abi Shaybah

Hazrat Mujahid says: The Messenger of Allah, peace and blessings be upon him, wrote a letter to my grandfather. And this blessed letter of the Prophet, peace and blessings be upon him, is with us. "In the name of Allah, the Most Gracious, the Most Merciful. This letter is to Dhi Murran Umair and to the Muslims of Hamdan. Peace be upon you! I praise before you Allah, besides whom there is no deity. After that! On our return from the land of Rome, news of your acceptance of Islam reached us. So glad tidings to you, for Allah has granted you guidance from His guidance. And when you people testified that there is no deity except Allah and that Muhammad is the Messenger of Allah (peace and blessings be upon him), and you established prayer and paid zakat, then for you is the guarantee of Allah and His Messenger (peace and blessings be upon him) over your wealth and your blood, and the level land on which you embraced Islam, its mountains, its springs, and its pastures are yours. Neither will you be wronged nor will you be oppressed. So indeed, charity (its wealth) is not lawful for Muhammad and the family of Muhammad (peace and blessings be upon him). This is the zakat by which you purify your wealth by giving this zakat to the poor Muslims. Indeed, Malik bin Murarah Rahawi remembered the unseen matters and conveyed the news. And O Dhi Murran! I command you to do good with him, for he is favored. And this letter was written by Ali (may Allah be pleased with him) bin Abi Talib. And peace be upon you. May your Lord send peace upon you."
