The Prophetic traditions are established Sunnahs.
Arriving early for the Friday prayer:
On the authority of Abu Hurayrah (may Allah be pleased with him), who said:
The Messenger of Allah (peace and blessings of Allah be upon him) said:
"When Friday comes,
angels stand at the door of the mosque,
recording people in order of their arrival.
The parable of the one who arrives early—
meaning the one who comes in the earliest hour—
is like one who offers a camel as a sacrifice;
the next is like one who offers a cow;
then like one who offers a horned ram;
then like one who offers a chicken;
then like one who offers an egg.
But when the Imam comes out,
they fold up their scrolls and sit down to listen to the remembrance."
Agreed upon.
