Sunni problem is that a Sahabi is not rated based on their emaan rather it is based on just the fact that they were in the company of Rasool pbuh or they have seen him even just once. The sahih bukhari and muslim both narates that;
The messenger of God, talking to his companions, said, "On the Day of Judgment, some of my Umma (community) will be taken to the left, and I will say; "to where ?". I will be told "to the Hell fire" I will say; "God, these were my (Sahaba) companions." I will be told that "You do not know what they invented after you. They turn back on their heel since you left them." I will say' " To destruction, destruction to those who changed things after me"
even Quran says many times about companions;
[9:74] "They swear by GOD that they never said it, although they have uttered the word of disbelief; they have disbelieved after becoming submitters. In fact, they gave up what
they never had. They have rebelled even though GOD and His messenger have showered them with His grace and provisions. If they repent, it would be best for them. But if they turn away, GOD will commit them to painful retribution in this life and in the Hereafter. They will find no one on earth to be their lord and master."
[9:75] "Some of them even pledged: "If GOD showered us with His grace, we would be charitable, and would lead a righteous life."
[9:76] "But when He did shower them with His provisions, they became stingy, and turned away in aversion."
[63:1] "When the hypocrites come to you they say, "We bear witness that you are the messenger of GOD."* GOD knows that you are His messenger, and GOD bears witness that the hypocrites are liars. "
[47:16] "Some of them listen to you, then as soon as they leave they ask those who were enlightened, "What did he just say?" GOD thus seals their hearts and, consequently, they
follow only their opinions."
[33:12] "The hypocrites and those with doubts in their hearts said, "What GOD and His messenger promised us was no more than an illusion!"
[9:58] "Some of them criticize your distribution of the charities; if they are given therefrom, they become satisfied, but if they are not given therefrom, they become objectors."
[9:61] "Some of them hurt the prophet by saying, "He is all ears!" Say, "It is better for you that he listens to you. He believes in GOD, and trusts the believers. He is a mercy for those among you who believe." Those who hurt GOD's messenger have incurred a painful retribution."
Not all Sahabi were good and you all know that, but some of you still consider them more pious then Ahlulbait and this is because of the blood lineage.
