Should Hadhrat stop the janazah salah from being offered outside the mosque?

I saw that we are exiting our mosque in order to pray a janazah salah outside. I am going outside along with them. However a person from behind says that the particular salah should be offered inside the mosque. I heard it and therefore abstained from offering it. However as I am moving to the location where the salah is being offered I saw that to a distance from me our beloved Prophet Muhammad (PUBH) appeared and Hadhrat too is moving to the location where the salah is being offered but he wants to stop them from offering the salah. He was surrounded by the rehmat of ALLAH (SWT) which appeared like little water droplets, all around our Prophet (PBUH). However I did not see the beard of Rasulullah on Hadhrat’s face. As far as I remember I also held and pulled my grandfather (passed away) up from behind due to something on the ground. The salah had already begun and Hadhrat was waiting for it to end sitting as there were a few chairs placed behind.
