Ata'ee barabari is both rationally impossible and shara'i impossible, proof is Allah does not create equals and we are not to set up equals with Allah It is equality in a rank or wujud as both are equal/barabari in knowledge I gave details of what I meant when people (including myself) are confronted with this allegation we do not contest it being association we say we believe in less than a drop from the oceans in comparison. I have never previously seen anyone contest this. What I said and meant was 1/4, half or full barabari are all blasphemous terms/comparisons. Further ata'ee barabari does not exist and could not be a basis for not doing takfir. This last point is the subject of discussion if ata'ee barabari is the key qualification and basis for not doing takfir. There is however a few possible explanations as to what the basis for not doing takfir is. If I understood correctly your explanation is: ata'ee barabari (in knowledge) exists as a rational or shara'i possibility, it is not association and is the basis of not doing takfir.
