Everything that goes against your mind set and planned ideology is weak, false etc. You decide if it is weak and your criteria for weakness and or falsehood??? Well you don't have one. You need to protect Sakeefa, justify Khilafath through what ever and which ever means necessary and certain companions just didn't get anything wrong, even when they were companions and especially when they became Khalifs. But certain companions and members of the Ahlul Baith did get it wrong. Well this just sums you exactly up!
While your mud slinging is far more representative of you, in Ahl as-Sunnah we don't accept narrations based on our ideology; heck our scholars narrated ahadeeth from all kinds of sects, including believe it or not, Shia. We base our authentication on five condition, بارك الله فيك:
1) A connection chain of narrators.
2) Everyone in the chain is upright (whether they are from a sect or not).
3) Everyone in the chain is considered strong in their memory and relaying of the text. If they are the hadeeth is considered Saheeh, if they are considered a lower level the scholars would lessed the hadeeth to the status of hassan.
4) It is not Shaath, or an outlier report. Meaning, we might get 5 reports all saying the same thing and one report saying something different. Even if that report has an authentic chain, it would be weakened because of this contradiction.
5) That there are not other irregularities that would cause a report to be inauthentic.
Now I ask you brother Ameen, how do your scholars authenticate reports?
