“Narrated Nu’am Al-Mujmir (radhiAllahu ‘anhu): Once I went up to the roof of the mosque, along with Abu Huraira. He performed ablution and said, “I heard the Prophet (sallAllahu ‘alayhi wa sallam) saying, ‘On the Day of Resurrection, my followers will be called “Al-Ghurr-ul-Muhajjalun” from the trace of ablution, and whoever can increase the area of his radiance should do so (i.e. by performing ablution regularly).’ “”
