Re: QUESTIONS TO A SHIA
Sure dear, take one example at the moment, its abou Hariz bin Uthman al Hamisi. Imam of Ahle Sunnah Ibn Hajar Asqalani records in Tahdeeb al Tahdeeb (excerpt):
Narrated in Al Bukhari and the four (i.e Sunan Abu Dawood, Sunan Al-Tirmidhi, Sunan Al-Nisa’i, Sunan Ibn Majah)… Mua’dh bin Mua’dh said: ‘I don’t think I saw some one in Shaam better than him’… Al-Ajuri said: ‘Abu Dawood said that all the Sheikhs of Hariz are authentic (Thiqat) and I asked Ahmad ibn Hanbal about Hariz to which he said: “Thiqah, Thiqah”’… Duhaim said: ‘His chain of narration (isnad) is sahih and said again: ‘Thiqah’’. Al-Mufadhal bin Ghasan said: “Thabt”… Ahmad bin Abi Yahya narrates that Ahmad (Ibn Hanbal) said: Hariz’s hadith is Sahih but he hated Ali… Al-Ejli said: ‘Thiqah and he hated Ali’. Amro bin Ali said : ‘He used to abuse Ali’… Hariz bin Uthman said: The tradition what the people narrate of the Holy prophet " Ali to me is what Haroon was to Musa" is right but the narrator heard it wrong, it is actually “Ali is to me what Qaroon was to Musa” …Ibn Haban narrated: “He used to curse Ali seventy times a day and seventy times a night”
Tahdeeb al Tahdeeb, Volume 1 No. 436
No need to mention that Qaroon was the enemy of Allah [swt] condemned in the Holy Quran (28:76-79. 29:39. etc). This impure creature had the audacity to equate Ali [as] with Qaroon, and hated, abused and cursed him (as). Despite this appalling behavior he is a Thiqa narrator of Sunni Hadith.
One who hate or abuse Ali bin Abi Talib [as] is munafiq or kafir according to both Shias and Sunnies and such person is known as ‘Nasibi’. While one who hate or abuse the rest of the three caliphs is called Rafidi. So according to pioneer Sunni ulema, Rafidi narrator is to be rejected but Nasibi is acceptable 
This reveals the ‘claim’ of their love for Ahlulbayt [as] , Ali bin Abi Talib [as] in particular. Double standards!!!
There many many more open Nawasib and Khawarij that are integral part of the books from which Ahle Sunnah take their religious teachings, or shall I say they actually take their teachings from those people as they are the ones on whom the books are dependent, and such people includes Abdullah bin Zaid bin Umro , Azhar bin Abdullah bin Jam’i al Hirazi , Khalid bin Abdullah bin Yazid , Naeem bin Abi Hind etc..
Thiqa, Thabt and other similar attributes are awarded for the one who is most reliable one.
