Hafidh of Shias Rajab al-Borsi said that sunnis would stay in the hell forever, this is the very same al-Borsi which accused mother of believers Aisha (r.a) in treachery!
In his book “ad-Door ath-Thamin fi Khamsmia Aya nazalat fi mawlana Amiralmuminin bi ittifaq aktharil mufasirin min ahl ad-deen”, at page 47 said:
And know! That wouldn’t stay in the fire (of the hell forever) anyone except disbelievers and friends of enemies of family of Muhammad (sallalahu alaihi wa ali). Because friends (mawali) of their enemies are their (ahlalbayts) enemies. And if he claims that he loves them, that is lie and shirk.
There is no doubt that each Muslim has great love and honour towards all companions, like Umar, Aisha, Talha and others. And these companions in accordance to shia belief were enemies of family of Muhammad (sallalahu alaihi wa ala alihi wa sallam). So, in accordance to this quote from shia hafidh, each sunni would stay in the hell forever due to his love of Umar or Aisha, even if he claims that he also loves Ahlalbayt.
