Here there are some Sunni Hadithes about why should 

All Muslims Love Hussain PBUH

 

Now, considering all these facts that Muslims Should love Hussain

look   at   this  ⤵️

Truly, what drove the Sunni Ummah to murder the  beloved grandson of their own beloved Prophet, the one whose presence among the members of Paradise is emphasized upon?

The one mentioned by the Prophet, as he says: ” Hussain is from me and I’m from Hussain” (both from Authentic Sunni hadiths) … Can a member of Paradise (Sunni ummah) murder another member of Paradise (Hussain) and yet be the right one? or only a member of Hell can murder a member of Paradise? indeed Quran indicates the second option. Those who hate and fight and kill the Believers are placed in hell, and indeed Hussain PBUH is a member of Paradise according authentic sunni Hadithes above. Therefore all those who fought Him and killed Him are members of Hell. Oh wait! Sunni scholars say that the arrow which killed Hussain was shooted at Saqifa and by the Members and Fans of Saqifa ..

So, who were they?? do the math yourselves!
