Allama of shias Muhammad ibn Muhammad ath-Thabzawari in his “Jami al-akhbar au maarij al yaqin fi usul ad deen” p 456 cited report:

Translation:

“And he – peace be upon him, said: Whoever will abuse me kill him, and whoever will abuse my companions accuse him in kufr.

And in other version of report: And whoever will abuse my companions beat him with stick”

As usual in foot note rafidi editor doing his best to explain that this is not about all companions.
