25:22
يَوْمَ يَرَ وْنَ ٱلْ مَلَٰٓئِكَةَ لَا بُشْرَىٰ يَوْمَئِذٍ لِّ لْ مُجْرِمِينَ وَ يَقُولُ ونَ حِجْرًا مَّحْجُورًا
The day they see the angels - no good tidings will there be that day for the criminals, and [the angels] will say, "Prevented and inaccessible."
25:53
وَ هُوَ ٱلَّذِى مَرَجَ ٱلْ بَحْرَيْنِ هَٰذَا عَذْبٌ فُرَاتٌ وَ هَٰذَا مِلْحٌ أُجَاجٌ وَ جَعَلَ بَيْنَ هُمَا بَرْزَخًا وَ حِجْرًا مَّحْجُورًا
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.
