Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) said: "Whoever walks toward Allah's authority on earth in order to humiliate it, Allah will humiliate his neck on the Day of Resurrection, in addition to what He has stored up for him in the Hereafter." Muslim added: Allah's authority means the Book of Allah and the Sunnah of His Prophet (peace and blessings be upon him).
