Abu Hurairah (May Allah be pleased with him) reported:
I heard the Messenger of Allah (ﷺ) saying: "On the Day of Resurrection, my followers (or Ummah) will be summoned 'Al-Ghurr Al-Muhajjalun' from the traces of Wudu'. Whoever can increase the area of his radiance should do so."[Al-Bukhari and Muslim].
