It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: Wherever the voice of the muezzin reaches, he is granted forgiveness to that extent, because every wet and dry thing bears witness in his favor. And for the one who participates in the congregational prayer, twenty-five good deeds are written, and the interval between two prayers becomes an expiation.
