It is narrated from Sayyiduna al-Sa'ib bin Yazid (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "No one will enter Paradise who has even a grain's weight of arrogance in his heart." The Companions said: O Messenger of Allah, then we are ruined! How are we to know whether that arrogance is in our hearts? And where is it? The Prophet (peace and blessings be upon him) said: "Whoever wears wool, or milks the goat himself, or eats with the slaves he owns, there is no arrogance in his heart, if Allah wills."
