وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ
And none is comparable to Him. (112:4)
Yakun is the jussive imperfect of the incomplete verb kāna, governed by lam. On a major parse, aḥadun is the delayed nominative name of yakun, while kufuwan is its advanced accusative predicate; lahu relates to that predicate. Another analysis takes lahu as predicate and kufuwan as a circumstantial accusative.
Despite the parsing alternatives the proposition still negates all equivalence or likeness to Allah. The alternatives should be represented honestly, without making an incidental syntactic choice the sole possible reading.
