«وسور السالبة الكلية في المتصلة والمنفصلة «ليس ألبتة»»
The universal negative marker for both connective and disjunctive conditionals is laysa al-batta.
Laysa al-batta indicates a universal denial of the relevant relation in the intended domain. In a negative connective it denies the claimed connection; in a negative disjunction it denies the claimed incompatibility.
The negation takes scope over the conditional relation. It need not independently deny every statement inside the antecedent or consequent.
