Assalamu Alaykum Ahsanallahu ilaykum I prayed salatul Jumu’ah but I had to pray in front of the Imam in an other room. I could pray on the sides next to those inside of the masjid but the security told us to go to the other room where we stand in front of the imam. Do I have to pray Dhuhr now?

The Fatwa of Imam Ibn Baz is: It is impermissible to perform the prayer ahead of the imam; the sound ruling is that one must not do so. Rather, the worshipper should stand behind the imam. Some scholars allow it only in exceptional circumstances; if a genuine necessity arises, the prayer is still considered valid. Even so, worshippers should be restrained from praying in front of the imam. They ought to stand behind him—or to his right or left—never before him. This is what is proper. Ps: in another fatwa for people who prayed in front of the Imam in the masjid of the Prophet ﷺ he said to repeat the salah.
