"What has increasingly happened in the last few decades is that many Muslims, it seems, have used and are using the criteria of the kuffar. Thus there has been, by them, a rejection, knowingly or unknowingly, of the fundamental Muslim truth that only Allah Subhanahu wa Ta'ala is the provider of ilm al-yaqin: of that knowledge about which we can be certain. Allah Subhanahu wa Ta'ala says: "They had no knowledge of such things: only assumptions, and assumptions are no guide to Truth." (53:28 Interpretation of Meaning). Instead of the criteria of the reliance upon Allah Subhanahu wa Ta'ala, there has been a reliance upon the fallible concepts, categories and ideas which the kuffar have manufactured and to which they have assigned names and terms, which concepts, categories and ideas the kuffar, and those following them or imitating them, believe give them, or will lead them to, understanding, knowledge, and truth. However, all these manufactured concepts, categories and ideas are based upon certain conjectures and assumptions which the kuffar have made."
