Some Muslims did not want to migrate to Medina with him, so Prophet Muhammad had to come out with several Quranic verses to intimidate and warn them: Quran Sura Al Anfal (8), verse 72.
And the ones who have believed, and have not emigrated, in no way are you to offer them patronage in anything untill they emigrate;

Muhammad even ordered Muslims to kill any Muslims who tried to return back to Mecca: Quran, Surah An-Nisa, verse 89 https://quran.com/an-nisa/89
They wish you would disbelieve as they have disbelieved, so you may all be alike. So do not take them as allies unless they emigrate in the cause of Allah. But if they turn away, then seize them and kill them wherever you find them, and do not take any of them as allies or helpers.
