question #1 Sahih Muslim 649i, Book 5, Hadith 342 : What is the significance of waiting in a place of worship for prayer in Islam?

The servant is constantly in prayer so long as he is in a place of worship waiting for the prayer (to be observed in congregation), and the angels invoke (blessings upon him in these words): O Allah! pardon him. O Allah! show mercy to him, (and they continue to do so) till he returns (from the mosque having completed the prayer) or his ablution breaks. I said: How is the ablution broken? He said: By breaking of the wind noiselessly or with noise.
