Remember the source’s base contrast: negated past + qaṭṭ; negated future + ʿawaḍ. Do not project the pattern indiscriminately onto unrelated adverbs.
Book example: مَا رَأَيْتُهُ قَطُّ.
I never saw him.
Past negation with qaṭṭ.
Book example: لَا أَضْرِبُهُ عَوْضُ.
I will never strike him.
Future negation with ʿawaḍ.
