Finally, one of the researcher mentions a valid point how come our Ulema doesn't put in parenthesis for certain companions who were reprimanded by Allah in the Qur'an i.e. Ka'ab ibn Malik (RA)? For, example where Allah is commending or praising a particular Sahabi or Aisha (RA) as a better example where Allah (SWT) defended her honour a book of tafsir will make this point very clearly with an explanation and quote Aisha somewhere in parenthesis but when it's the other way around it's never the case?
Our Sunni scholars guilty of doing this?
I didn't watch the video, بارك الله فيك, but I don't understand what you're asking about "parenthesis?" Are you saying our scholars رضي الله عنهم glorify the praise of the Companions رضي الله عنهم but hide their faults? If that's what you're asking then I have to things to say about that inshallah:
1) This is Islamic adab with Muslims we respect. When we use the statement of any of scholars to support our views, we usually quote them and use lofty titles and say رحمه الله after we mention it, and we refute a point, we just say, "some people" say. We aren't in the business of disrespecting Muslims who we came before us. This is especially the case with the Companions رضي الله عنهم. Think about this for example, do you know who the three companions were who said they would fast all the time, not get married, and pray all night every night? Didn't the Prophet صلى الله عليه وسلم go out and what "What is wrong with 'some people' who say 'such and such?" He صل الله عليه وسلم didn't name them by name, rather he just refuted what they did wrong and moved on. What about the "One Who Prayed Poorly", do you know his name?
2) Nonetheless, the reality is these stories are mentioned in all the books of tafsir; in fact, where did we get this stories from if not from the books of tafsir? The story of Ka'b ibn Malik رضي الله عنه is found in every book of tafsir that deals with this issue; how else can you explain the verse without that narration?
