“Fa-lammā tajallā rabbuhu lil-jabal”
“When his Lord manifested [His glory] to the mountain.” (al-Aʿrāf 7:143, excerpt)
The text uses the lām in “lil-jabal.” An explanatory expression with “ʿalā al-jabal” can help convey how the manifestation is related to the mountain. The surrounding account describes Moses’ request and the mountain’s inability to withstand the manifestation.
The point is the effect of the divine manifestation, not an assertion that God has a material location. A paraphrase of the particle must be controlled by the doctrinal and narrative context.
Particle substitution does not authorize new claims that the verse itself does not establish.
