Possible Meanings:

Tafsir Ar-Razi

“There could be a physical land mass barrier between them or there may not be”.

Reported views in Al-Qurtubi

Al-Qurtubi cites multiple views

  • The barrier is between the sky (heaven) and earth.
  • The barrier is the land between the two seas surrounding Arabia: Al-Hijaz.
  • The barrier is between the Dunya (worldly life) and the Akhirah (hereafter): a time period Allah determined, during which the two do not transgress; when Allah decides the end of the Dunya the two seas become one.

Note: These are quotes of others whom Al-Qurtubi cites.

Majority understanding

Fresh and salty seas

Fresh and salt water remain distinct

The opinion of the majority of Mufassireen is that the two seas are referring to the fresh water and the salt water.

“Allah, Exalted and Blessed is He, created the two seas, and by His power set them flowing in their courses, such that they meet and one touches the other. Yet they do not mix: the salty remains salty, and the fresh remains fresh. This is because Allah’s wisdom has decreed a separation between them, either by barriers of earthly matter or by inherent properties within each, that prevent them from mixing. Were it not for these properties and barriers, they would blend and merge. And this stands as one of the greatest signs of Allah’s power, Exalted is He”.

Key takeaways

Barrier and non-transgression

The ayah states the presence of a barrier (بَرْزَخٌ) such that neither side transgresses (لَا يَبْغِيَانِ).

Range of loci

Classical reports mention possibilities from cosmological (sky–earth) to geographical (Al‑Hijaz) to eschatological (Dunya–Akhirah), alongside readings about distinct seas.

Majority view summarized

Fresh and salt waters meet yet do not mix — separated by properties or barriers, manifesting a sign of Allah’s power.

Qualities prevent mixing

As Ibn ‘Ashour notes, each has special qualities that keep it distinct from the other.
