Wish you all here in advance 'Jummaah Mubarak'
"O believers, when the call is proclaimed for the prayer on Friday, come to the remembrance of Allah and leave off business, that is better for you if you but did know." [Al-Jumuah, 62:9]
Wish u all a happy Jummah Mubarak.
Pray for the Ummah.
Ameen

, or from the sahaabah (may Allah be pleased with them), that they used to themselves, or told other people to, offer each other congratulations because of it being the day of Jumu'ah. Therefore it's best if we don't make a habit of saying this, or think that it is virtuous to say this every Friday. However, we can remind each other of the virtues of Jumu'ah and the acts to be performed within it, and make du'aa for each other.
