Musannaf Ibn Abi Shaybah 37825 — The words of Umar bin Abd al-Aziz

It is narrated from Ja'far bin Burqan that he said: Umar bin Abd al-Aziz (may Allah have mercy on him) wrote a letter: To proceed: Indeed, some people seek the world through the deeds of the Hereafter, and some storytellers have innovated invoking blessings on their caliphs and governors as is done for the Prophet (peace and blessings be upon him). So when this letter of mine reaches you, order the people to invoke blessings on the Prophet (peace and blessings be upon him) and the other prophets, and that their supplication be for the Muslims in general, and that they leave everything other than that.
