Barrier

Al-Kahf 18:94

قَالُواْ يَٰذَا ٱلۡقَرۡنَيۡنِ إِنَّ يَأۡجُوجَ وَمَأۡجُوجَ مُفۡسِدُونَ فِي ٱلۡأَرۡضِ فَهَلۡ نَجۡعَلُ لَكَ خَرۡجًا عَلَىٰٓ أَن تَجۡعَلَ بَيۡنَنَا وَبَيۡنَهُمۡ سَدّٗا ٩٤

They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?"

Al-Kahf 18:95

قَالَ مَا مَكَّنِّي فِيهِ رَبِّي خَيۡرٞ فَأَعِينُونِي بِقُوَّةٍ أَجۡعَلۡ بَيۡنَكُمۡ وَبَيۡنَهُمۡ رَدۡمًا ٩٥

He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam.

Al-Furqān 25:53

۞ وَهُوَ ٱلَّذِي مَرَجَ ٱلۡبَحۡرَيۡنِ هَٰذَا عَذۡبٞ فُرَاتٞ وَهَٰذَا مِلۡحٌ أُجَاجٞ وَجَعَلَ بَيۡنَهُمَا بَرۡزَخٗا وَحِجۡرٗا مَّحۡجُورٗا ٥٣

And it is He who has released [simultaneously] the two seas, one fresh and sweet and one salty and bitter, and He placed between them a barrier and prohibiting partition.

An-Naml 27:61

أَمَّن جَعَلَ ٱلۡأَرۡضَ قَرَارٗا وَجَعَلَ خِلَٰلَهَآ أَنۡهَٰرٗا وَجَعَلَ لَهَا رَوَٰسِيَ وَجَعَلَ بَيۡنَ ٱلۡبَحۡرَيۡنِ حَاجِزًاۗ أَءِلَٰهٞ مَّعَ ٱللَّهِۚ بَلۡ أَكۡثَرُهُمۡ لَا يَعۡلَمُونَ ٦١

Is He [not best] who made the earth a stable ground and placed within it rivers and made for it firmly set mountains and placed between the two seas a barrier? Is there a deity with Allah? [No], but most of them do not know.

Saba’ 34:54

وَحِيلَ بَيۡنَهُمۡ وَبَيۡنَ مَا يَشۡتَهُونَ كَمَا فُعِلَ بِأَشۡيَاعِهِم مِّن قَبۡلُۚ إِنَّهُمۡ كَانُواْ فِي شَكّٖ مُّرِيبِۭ ٥٤

And prevention will be placed between them and what they desire, as was done with their kind before. Indeed, they were in disquieting denial.

Yā-Sīn 36:9

وَجَعَلۡنَا مِنۢ بَيۡنِ أَيۡدِيهِمۡ سَدّٗا وَمِنۡ خَلۡفِهِمۡ سَدّٗا فَأَغۡشَيۡنَٰهُمۡ فَهُمۡ لَا يُبۡصِرُونَ ٩

And We have put before them a barrier and behind them a barrier and covered them, so they do not see.

Ar-Raḥmān 55:19

مَرَجَ ٱلۡبَحۡرَيۡنِ يَلۡتَقِيَانِ ١٩

He released the two seas, meeting [side by side];

Ar-Raḥmān 55:20

بَيۡنَهُمَا بَرۡزَخٞ لَّا يَبۡغِيَانِ ٢٠

Between them is a barrier [so] neither of them transgresses.
