Definition:
Al-Tadhjil: adding an independent-meaning clause after a preceding clause to reinforce and confirm it — like a proverb that is cited to establish a point.
Two types:
- The proverb-like type: Can stand alone as evidence — like well-known maxims.
- The non-proverb type: Its full meaning depends on what precedes it.
Quranic examples:
- "Say: Truth has come and falsehood has vanished — indeed falsehood is ever bound to vanish" (17:81) — "falsehood is ever bound to vanish" is an independent tadhjil establishing the removal of falsehood as a universal principle.
- "Allah would not punish them while you are among them, nor would He punish them while they seek forgiveness" (8:33) — the second clause is an independent tadhjil with a separate reason for the lifting of punishment.
- "It is not the eyes that go blind but the hearts within the chests" (22:46) — a tadhjil establishing the law of true blindness.
Difference from repetition:
Repetition restates the same wording — tadhjil brings a new meaning that is broader and more encompassing, confirming what came before.
Question: What is the tadhjil in "indeed falsehood is ever bound to vanish" (17:81)? How does it differ from repetition?
Answer: Tadhjil: an independent clause confirming what preceded it in a more general formulation — "falsehood is ever bound to vanish" establishes it as a universal law. The difference: repetition restates the wording; tadhjil brings a broader meaning.
