From my limited Arabic, having a look at the literal meanings, the following errors do indeed amount to kufr meanings, some of them being very serious 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12, 14, 15, 16, 18, 20 My Arabic/knowledge of Islam is not good enough to comment on errors numbered 4, 13, 17, 19 if it is kufr or not. May Allah forgive me if I made any mistake. Any knowledgeable brothers or sisters who see any mistake in what I said, please do point it out.
