question #3 Sahih Muslim 649k, Book 5, Hadith 344 : What are the blessings invoked by angels for someone who remains in a state of ablution while waiting for prayer?

The Messenger of Allah (ﷺ) said: Anyone amongst you who sat in a place of worship waiting for the prayer is in prayer and his ablution is not broken, the angels invoke blessing upon him (in these words): O Allah! pardon him. O Allah! have mercy upon him.
