It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) saw Sayyiduna Umar (may Allah be pleased with him) wearing white clothes. The Prophet (peace and blessings be upon him) asked him, "Are your clothes new or washed?" I do not remember what he replied to the Prophet (peace and blessings be upon him), but the Prophet (peace and blessings be upon him) said: "Wear new clothes, live a praiseworthy life, and die the death of martyrs, and he also probably said: May Allah grant you the coolness of the eyes in this world and the Hereafter."
