It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: On the Day of Resurrection, I will recognize every individual of my Ummah. The noble Companions asked: O Messenger of Allah! Will you recognize each one, whether you have seen them or not? He (peace and blessings be upon him) replied: Whether I have seen them or not, their foreheads and hands and feet will be shining because of ablution.
