Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) says: We were present with the Messenger of Allah (peace and blessings be upon him), when a resident of a town came wearing a cloak of Sijjan, whose buttons were of silk, and said: Beware! Your companion (Muhammad, peace and blessings be upon him) has lowered the status of horsemen and elevated the honor of shepherds. The Messenger of Allah (peace and blessings be upon him) grabbed him by the collar of his cloak and said: "Do I not see upon you the clothing of those who are foolish?" Then he said: "When the time of death of Allah’s Prophet Nuh (peace be upon him) approached, he said to his son: I am going to state a will before you. I command you with two things and forbid you from two things. I command you with «لا إله إلا الله», for if the seven heavens and the seven earths were placed on one side of the scale and «لا إله إلا الله» on the other side, «لا إله إلا الله» would outweigh them. And if the seven heavens and the seven earths were to take the form of a closed ring, «لا إله إلا الله» would break it. And (the second thing) is «سبحان الله و بحمده»; these words are the prayer of everything and through them the creation is provided sustenance. And I forbid you from shirk and arrogance." I or someone else said: O Messenger of Allah! We recognize shirk, but what is arrogance? Is arrogance that a man’s shoes and their straps are good? The Messenger of Allah (peace and blessings be upon him) said: "No." Someone said: Then is arrogance that a man has friends who sit with him? The Prophet (peace and blessings be upon him) said: "No." Then someone said: O Messenger of Allah! Then what is arrogance? He (peace and blessings be upon him) said: "Rejecting the truth and looking down upon people (is called arrogance)."
