In tashbih baligh, both the particle and the ground are omitted, creating a compact and forceful predication.
«الْعَالِمُ نُورٌ»
The scholar is light.
The scholar and light are the two terms; neither a particle nor an explicit ground is present. The expression is both muʾakkad and mujmal.
Not every muʾakkad comparison is baligh: “he is a sea in generosity” still explicitly states its ground.
