It was narrated from 'Abd-Allaah ibn Mas'ood that the Prophet (peace and blessings of Allaah be upon him) said: "No one who has an atom's-weight of arrogance in his heart will enter Paradise." A man said, "O Messenger of Allaah, what if a man likes his clothes and his shoes to look good?" He said, "Allaah is Beautiful and loves beauty. Arrogance means rejecting the truth and looking down on people."
