Nabi' s.a.w said

Narrated Nu'am Al-Mujmir (Radi-Allahu '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 'Alaihi WaSallam) saying, 'On
the Day of Resurrection,my followers will be called"Al-Ghurr-ul-Mu
hajjalun" from the trace of ablution, and whoever can increase the
area of his radiance should do so (i.e. by performing ablution
regularly).' "
