Salamun Alaikum. can we receite Namaz e Juma with Wajib Niyyat? what is the rule of Zohar Namaz if we receite Juma Namaz with Wajib Niyyat? Wsalam

It is wajib-e takhyeri, meaning it is obligatory but optional at the same time; that is, if a person performs Friday prayer, he does not have to say Zohr.
