The Holy Quran 55:20 — Surah Ar-Rahman

Arabic text

بَيْنَهُمَا بَرْزَخٌ لَّا يَبْغِيَانِ

Translation

(However,) Between the two (waters) is a (invisible) barrier so that the two do not transgress (do not mix with each other).

Tafsir (excerpt) — Tafsir Usmani

Some explanation concerning the subject of this verse has already been given towards the end of Surah Al-Furqan; let it be consulted.
