It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that someone asked the Messenger of Allah (peace and blessings be upon him): "How will you recognize those individuals of your Ummah whom you have not seen?" He (peace and blessings be upon him) replied: "Surely, due to the effects of ablution, their foreheads, hands, and feet will be shining and radiant."
