I am just curious why is it causing an uproar?

It is causing an uproar for a number of reasons. Basically what has happened is this person quoting this narration is presenting himself as a "Sufi" of some sort. From all indications to me, he is a Barelvi based on many of the practices that I see him observe and his penchant for narrating weak hadith on nearly every subject.

The uproar has come because the Arabs, Deobandis, and Salafi-types in our masjid have critiqued the narration on a number of grounds, especially because the claim that the Rasul (peace be upon him) asked this person what his sin was, since that is not consistent with what we see in the bulk of the hadith, and because the person in this narration appears to have been, may Allah save us, ignorant of the fact that Allah forgives all sins but shirk! Furthermore, the fact that in none of the more famous Tafsirs that we have at our disposal at our masjid, such as Ibn Kathir, Jalalayn, Nasafi, etc. do we see this narration. On the opposite side, the Barelvis or bidah-inclined laymen are insisting upon the reliability of the narration AND they are insisting on keeping this person as a halaqah leader and/or part-time Khateeb and the rest of us are opposed to this because of this person's penchant for narrating these strange stories that appear to appeal to Barelvis and those who love dramatic narrations.

I hope that this clears it up.
