question #2 Sahih Muslim 649h, Book 5, Hadith 341 : How does maintaining ablution affect the blessings and mercy invoked by angels?

The angels invoke blessings on everyone among you so long as he is in a place of worship with these words: O Allah! pardon him, O Allah, have mercy upon him, (and they continue to do so) as long as, he ablution (of the worshipper) is not broken, and one among you is in prayer and so long as he is detained for the prayer.
