It is narrated from Sayyiduna Abu Sa'id (may Allah be pleased with him) that the Companions (may Allah be pleased with them) said: "O Messenger of Allah, how will you recognise those of your ummah whom you have not seen?" He (peace and blessings be upon him) said: "Their faces, hands and feet will be bright and shining from the traces of ablution (wudu)."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Hasan bin Husayn narrated this hadith from Abu Isra'il."
