LISTEN TO THE SERMON IN SILENCE H 1171 "For whosoever makes his ablution carefully and then attends the congregational Friday prayer and listens to the sermon in silence is the forgiveness of his sins since the previous Friday plus three extra days. But whosoever occupies himself with pebbles during the sermon misbehaves." R 1171 Muslim with a chain up to Abu Hurairah who related that the Messenger of Allah, praise and peace be upon him, said this.
