The angels supplicate in favour of one of you so long as he remains in the place where he has performed Salat (prayer)

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu ’alayhi wa sallam) said,

The angels supplicate in favour of one of you so long as he remains in the place where he has performed Salat (prayer) in a state of Wudu’. They (the angels) say: `O Allah! Forgive him, O Allah! Have mercy on him

[Sahih Al-Bukhari]
