Sheikh Fawzan was asked the following question:
Every Friday one of my colleagues sends me a text saying “Ju’muaah Mubaarak” and he continues saying that he hopes that I will add that to my cell phone greeting or to my greeting on the internet forums; what is your view of this?
Answer: Sheikh Fawzan
This is an innovation, Allah has not sent down any authority for this action. This is an action that is not known or narrated in the Sunnah; it has not been narrated that the Muslims should congratulate each other on Friday; rather it has only been reported that they would congratulate each other on Eid Al Adha and Eid Al Fitr not on Friday.Therefore putting this is a text and encouraging others to do it is an innovation and from spreading innovation.
Sheikh Abdul Musin Al Abaad was asked the following question:
Based on the premise that Friday is a (Eid) holiday, is it permissible to greet each other saying, Ju’muaah Mubaarak or Ju’muaah Accepted?
Answer: Sheikh Abdul Musin Al Abaad:
By Allah, we don’t know of anything that proves the validity of this. As for the two Eids then it has been narrated that the companions when they would meet each other they would say, “May Allah accept it from us and you” or “May Allah accept your obedience”.

The Mufti Sheikh Abdul Aziz was asked the following question:
What is the ruling on the statement Ju’muaah Mubaarak?
Answer: Sheikh Abdul Aziz
There is no origin for sending out the greeting Ju’muaah Mubaarak on the cell phones. It is a bless day, no doubt.Allah the Exalted has singled us out with this day, and the Jews and Christians have been lead astray away from this day, but as for giving a greeting every Friday then we don’t know of any origin for this.

What is the ruling on offering congratulations on Friday?
What is the ruling on offering congratulations on Friday, because now it is the custom in our country on Friday to send text messages and people congratulate one another on the occasion of Friday by saying “Jumu‘ah mubaarak” or “Jumu‘ah tayyibah”.
Ibn al-Qayyim (may Allah have mercy on him) said, describing the special virtues of Friday:
Thirteen: It is a day of ‘Eid that is repeated every week.
Zaad al-Ma‘aad, 1/369
Thus the Muslims have three Eids: Eid al-Fitr and Eid al-Adha, which come once every year, and Jumu‘ah which is repeated once every week.
Secondly:
With regard to the Muslims congratulating one another on the occasions of Eid al-Fitr and Eid al-Adha, this is prescribed and it is narrated from the Sahaabah (may Allah be pleased with them). This has been discussed previously in the answers to questions no. 49021 and 36442. As for congratulating one another on the occasion of Friday, what seems to us to be the case is that it is not prescribed, because the fact that Friday is an Eid was known to the Sahaabah (may Allah be pleased with them), and they were more knowledgeable than us about its virtues, and they were keen to respect it and give it its due, but there is no report to suggest that they used to congratulate one another on Fridays. And all goodness is in following them (may Allah be pleased with them).
Shaykh Saalih ibn Fawzaan (may Allah preserve him) was asked: What is the ruling on sending text messages every Friday and ending with the phrase “Jumu‘ah mubaarak”?
He replied:
The early generation did not congratulate one another on Fridays, so we should not introduce anything that they did not do.
