Musnad Ahmad 28:621

Wahb ibn Jarir narrated to us, my father narrated to us, I heard al-Saq'ab ibn Zuhayr narrating from Zayd ibn Aslam, from 'Ata' ibn Yasar, from 'Abdullah ibn 'Amr, who said: A Bedouin came to the Prophet, peace and blessings of Allah be upon him, wearing a cloak of *tayalisa* (Persian-style shawl) hemmed with silk, or buttoned with silk. He said: "This companion of yours wants to raise every shepherd who is the son of a shepherd, and lower every horseman who is the son of a horseman." The Prophet, peace and blessings of Allah be upon him, stood up in anger, took hold of the folds of his cloak, and pulled him, saying: "I do not see upon you the clothing of one who possesses intellect." Then the Messenger of Allah, peace and blessings of Allah be upon him, returned and sat down. He said: "When death approached Noah, peace be upon him, he called his two sons and said: 'I am entrusting you with a testament. I command you with two things and I forbid you from two things. I forbid you from *shirk* (associating partners with Allah) and arrogance. And I command you with *La ilaha illa Allah* (there is no god but Allah), for if the heavens and the earth and all that is within them were placed in one scale of the balance, and *La ilaha illa Allah* were placed in the other scale, it would outweigh them. And if the heavens and the earth were a solid ring, and *La ilaha illa Allah* were placed upon them, it would break them or shatter them. And I command you with *Subhan Allah wa bi-hamdihi* (Glory be to Allah and by His praise), for it is the prayer of everything, and by it, everything is provided for.'"
