this wishing has been spread over social networking, it has no sens in Arabs or Muslims typical day. Better to say: have a nice day (نهارك سعيد ) Or ( صباحك سعيد ، مساءك سعيد ، تصبح على خير )

say جمعه مباركه

Does that mean 'happy Friday'? If it does, then it is already in Arabic, but I am afraid I know of no Arabs who normally congratulate one another on Fridays. Muslims do consider Friday 'a feast', but beyond many of them taking the day off, this amounts to little.

we say the same ( jumah mubaraka) ,it's written like this : جمعة مباركة
