At-Tuġyān is interpreted in four ways:
1. At-Tuġyān is used in the sense of dalāla (misguidance); as in the following verses:
He leaves them blindly wandering in their tuġyān {that is, their dalāla (misguidance)}. (al-Baqara 2:15)
We leave those who do not expect to meet Us in their tuġyān {that is, their dalāla (misguidance)}, wandering blindly. (Yūnus 10:11)
Our Lord! I did not cause him to commit tuġyān {that is, I did not lead him into dalāla (misguidance)}; but he was in deep dalāla (misguidance) himself. (Qāf 50:27)
Rather, you were a people who had committed tuġyān {that is, who had fallen into dalāla (misguidance)}. (al-Ṣāffāt 37:30)
So it is. But for the ones who have committed tuġyān {that is, who have fallen into dalāla (misguidance)}, there is surely an evil place of return. (Ṣād 38:55)
A similar statement also appears in Sūrat al-Nabaʾ.
2. Tuġyān is used in the sense of isyān (rebellion); as in the following verses:
Go to Pharaoh; indeed, he has committed tuġyān {that is, he has rebelled against Allah}. (Ṭā-Hā 20:24)
Do not commit tuġyān therein {that is, do not rebel against Allah by hoarding manna and quails}. (Ṭā-Hā 20:81)
3. At-Tuġyān is used in the sense of elevation and abundance; as in the following verse:
Indeed, when the water committed tuġyān {that is, when the water increased and rose}, We carried you in the ship. (al-Ḥāqqa 69:11)
4. At-Tuġyān is used in the sense of ẓulm (injustice); as in the following verses:
The sight did not swerve, nor did it commit tuġyān/exceed the limit. (al-Najm 53:17) Do not commit tuġyān {that is, do not commit ẓulm (injustice)} in the balance! (al-Raḥmān 55:8)
