Summary:
- رَيْبَ deals with doubt or uncertainty in belief or perception.
- عِوَجًا relates to a lack of straightness or alignment, implying perfection and consistency.
Together, these terms underline the Quran’s clarity, authenticity, and flawlessness in both meaning and structure.
Comparison of the Two:
| Aspect | رَيْبَ (Raib) | عِوَجًا (Iwaj) |
|---|---|---|
| Core Meaning | Doubt, uncertainty, or suspicion. | Crookedness, deviation, or error. |
| Context | Intellectual or emotional doubt about truth or authenticity. | Structural or moral deviation from uprightness. |
| Focus | Truth vs. doubt. | Straightness vs. distortion. |
| Example | Quran has no doubt (رَيْبَ) in its guidance (2:2). | Quran is free of crookedness (عِوَجًا) in its content (18:1-2). |
