Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Prophet Muhammad (peace and blessings be upon him): "Do not pluck out white hairs, for they will be light on the Day of Resurrection. And whoever grows old in Islam (i.e., his hair turns white), good deeds will be written for him in exchange for them, his sins will be forgiven in exchange for them, and his ranks will be elevated in exchange for them."
