What are the textual proofs from the Qur'an and Sunna that ALL the Companions(ra) (i.e. each and every one, with no exceptions whatsoever) were upright ('adl)? (Please excuse the capitals here and below. It's for emphasis and I'm not shouting.)
I understand a Companion to be anyone who saw the Prophet(s) in a state of belief, carried on in that state of belief, and subsequently died in that state of belief.
I have also been taught that each and every one of the Companions(ra) was 'adl (upright), with no exceptions. But what are the textual proofs for this?
My problem is this: I am familiar with many of the verses or hadiths cited in this context, but how do they support the conclusion that EACH AND EVERY SINGLE COMPANION is righteous, without exception?
For example, the verse You are the best community brought forth for the good of mankind (3:110), is normally cited in this context. But this verse seems to be a general address which doesn't necessitate our thinking that EACH AND EVERY SINGLE Companion was upright. Some scholars interpret it as referring to the community of Muslims as a whole, and we know for sure that many of these are not righteous, so how does the language suport the conclusion that ALL the members of the community referred to are righteous? Could it not just mean that the community AS A WHOLE was righteous? Moreover, I have been told by a scholar that according to Sayyiduna Ibn Abbas (ra), the verse refers to the Muhajirun and the Ansar, and there were many Companions who were not among the Muhajirun and the Ansar.
Similarly, when Allah(swt) says "Allah is well pleased with them", referring to the Companions, could this not mean that "Allah is well pleased with them as a whole", without meaning that EACH AND EVERY ONE OF THEM is upright?
