Miraj was so confused after a meeting with that witch from the Joroffs ─ she found out his name was Keyan and he was a step son of Jeremiah, so it was Jeremiah who indeed sent him to persuade Miraj into going after Nazar by giving her his most sacred secret and that was his plans to sacrifice Simon at the rocks of Cairo so that to bring Rasheeda back.
Jeremiah didn't have any objection on Nazar bringing Rasheeda back, it wouldn't have affected any of his plans since Rasheeda was just a lost cause. She didn't have any power; she was neither a witch nor a vampire but just a mere human who Lunara murdered when she found out that she was having an affair with Nazar.
