Hadith 649 Part F

A man's prayer in congregation is more valuable than twenty degrees and some above them as compared with his prayer in his house and his market, for when he performs ablution doing it well, then goes out to the mosque, and he is impelled (to do so) only by (the love of congregational) prayer, he has no other objective before him but prayer. He does not take a step without being raised a degree for it and having a sin remitted for it, till he enters the mosque, and when he is busy in prayer after having entered the mosque. the angels continue to invoke blessing on him as long as he is in his place of worship. saying: O Allah, show him mercy, and pardon him! Accept his repentance (and the angels continue this supplication for him) so long as he does not do any harm in it, or as long as his ablution is not broken.
