In an affirmative command, aw may offer alternatives. In a negative oath, however, the textbook treats the prohibition as reaching each mentioned object.
«لا آكل هذا أو هذا»
I will not eat this or that.
Avoiding only one item does not license eating the other. In the juristic example, consuming either mentioned item breaches the oath. The scope of aw must therefore be read in its affirmative or negative context.
