Denier treated as non-denierAdditional emphasis may be omittedDenial is discounted because of evidence
Existing doubts treated as absent«لَا رَيْبَ فِيهِ» categorically negates doubtEvidence capable of removing doubt is available

Preserving this distinction is essential to the argument’s accuracy.
