The final counsel of Noah (peace be upon him)

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates: We were with the Prophet (peace and blessings be upon him) when a man from the desert came, wearing a cloak of sijan with buttons of silk brocade. He said: "Beware! This companion of yours has brought down every horseman son of a horseman!" The narrator says: He also said: "He wants to bring down every horseman son of a horseman and raise up every shepherd son of a shepherd!" The Prophet (peace and blessings be upon him) took hold of the edges of his cloak and said: "Do I not see on you the clothing of one who has no sense?" Then the Prophet (peace and blessings be upon him) said: "When the time of death drew near for the Prophet of Allah, Sayyiduna Nuh (peace be upon him), he said to his son: 'I am about to give you my will. I will command you to do two things and forbid you from two things. I command you to say La ilaha illallah (there is no god but Allah), for if the seven heavens and the seven earths were placed in one pan of the scale and La ilaha illallah were placed in the other pan, the pan of La ilaha illallah would outweigh them; and if the seven heavens and the seven earths were a closed ring, La ilaha illallah and Subhan Allah wa bihamdihi (Glory be to Allah and praise be to Him) would break them. This is the prayer of everything, and through it creation is given provision. And I forbid you from associating partners with Allah and from arrogance.'" The narrator says: I said: "O Messenger of Allah! As for associating partners, we have understood that; what is meant by arrogance? Does arrogance mean that one of us has good sandals with good straps?" The Prophet (peace and blessings be upon him) said: "No." He asked: "Does it mean that one of us has a fine suit of clothes which he wears?" The Prophet (peace and blessings be upon him) said: "No." He asked: "Does it mean that someone has a riding animal which he rides?" The Prophet (peace and blessings be upon him) said: "No." He asked: "Then does it mean that one of us has companions who sit with him?" The Prophet (peace and blessings be upon him) said: "No." It was said: "O Messenger of Allah! Then what is arrogance?" The Prophet (peace and blessings be upon him) said: "Belittling the truth and looking down on people."

In a narration from him, the wording is: He said: A Bedouin came to the Prophet (peace and blessings be upon him), wearing a Tayalisi cloak trimmed with brocade. Then the narrator mentioned the narration as before, except that in it the wording is: Then the Prophet (peace and blessings be upon him) returned and sat down, and he said: "When the time of death drew near for Sayyiduna Nuh (peace be upon him), he called his two sons and said: 'I am going to give you a brief bequest. I will command you to do two things and I will forbid you two things. I forbid you both from associating partners with Allah (shirk) and from arrogance, and I command you both to say La ilaha illallah (there is no god but Allah), for if all the heavens and the earth and everything between them were placed in one pan of the scale, and La ilaha illallah were placed in the other pan, that pan would outweigh them; and if all the heavens and the earth were a ring and La ilaha illallah were placed upon them, it would break them apart.'" Ahmad recorded all of these narrations. Al-Tabarani recorded something similar, and in one narration he added the words: "I enjoin you to say Subhan Allah (glory be to Allah), for it is the worship of all creation, and I enjoin you to say the takbir."
Al-Bazzar recorded it as a hadith narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both), and I have mentioned it in the chapter on adhkar (remembrances), in the section on the virtue of La ilaha illallah. The narrators of Ahmad are thiqat (trustworthy).
