وَنِهَايَةٍ مِنْ حُسْنِ التَّنْظِيمِ وَالتَّرْتِيبِ
And with exceptional coherence of arrangement and sequence.
Tanẓīm brings related elements into a coherent whole; tartīb puts them in a suitable order. The purpose is not decorative headings but a sequence through which a learner can follow an argument.
A workable sequence:
1. Define the term.
2. State and qualify the claim.
3. Offer its evidence.
4. Examine its implications and objections.
5. State the conclusion.
A statement may be correct yet hard to understand if the conclusion appears before the premises required to grasp it.
