On previous link I learned that there is no khilāf in ‘Aqīdah between the Sahāba, but that the khilāf is in the furu’.
I recently read an argument about that there is khilāf about what was created first, the Pen or… And the reply beautified my steadfastness that this issue can’t be used as a critic to the claim that there is no khilāf in ‘Aqīdah. Because the reply was, that there is no khilāf in affirming and negating what was created, the Pen, the Water, the Throne, etc.; every Sahābi acknowledges the existence of these. This means that when you ask about what was created first, then you get out from the circle of negating and affirming, which means that it comes under the heading of furu’.
