(meeting together.) Ibn Zayd said, "He prevents them from meeting by the dividing barrier He placed between them to separate them.'' The two seas are the fresh and salty waters, the former coming from running rivers. We discussed this topic in Surat Al-Furqan when explaining Allah's statement;

[وَهُوَ الَّذِى مَرَجَ الْبَحْرَيْنِ هَـذَا عَذْبٌ فُرَاتٌ وَهَـذَا مِلْحٌ أُجَاجٌ وَجَعَلَ بَيْنَهُمَا بَرْزَخاً وَحِجْراً مَّحْجُوراً ]

(And it is He Who has let free the two seas: one palatable and sweet, and the other salty and bitter; and He has set a barrier and a complete partition between them.)(25:53) Allah said,

[بَيْنَهُمَا بَرْزَخٌ لاَّ يَبْغِيَانِ ]

(Between them is a barrier which none of them can transgress.) meaning, He has placed a barrier of land between these two types of waters, so that they do not transgress upon each other, which would spoil the characteristics they were created with. Allah said,

[يَخْرُجُ مِنْهُمَا الُّلؤْلُؤُ وَالمَرْجَانُ ]

(Out of them both come out pearls and Al-Marjan. ) pearls are well-known. As for Marjan they say it means small pearls. Mujahid, Qatadah, Abu Ruzayn, Ad-Dahhak said it, and it has also been reported from `Ali. It was also said that it means large, precious pearls, this was mentioned by Ibn Jarir from some of the Salaf. Ibn Abi Hatim recorded from Ibn `Abbas who said, "When it rains, the oysters in the sea open their mouths. What falls in them, the drops, turns into pearls.'' Its chain of narrators is Sahih. Since this type of adornment is a favor from Allah to the people of earth, He reminded them of it,

[فَبِأَىِّ ءَالاءِ رَبِّكُمَا تُكَذِّبَانِ ]

(Then which of the blessings of your Lord will you both deny) Allah said,

[وَلَهُ الْجَوَارِ الْمُنشَئَاتُ]

(And His are Al-Jawar Al-Munsha'at), meaning the ships that float,

[فِى الْبَحْرِ]

(in the seas), Mujahid said, "Whatever ship hoists a sail, it is from Munsha'at, if it does not hoist a sail, it is not from the Munsha'at.'' Qatadah said, "Al-Munsha'at means created.'' Others said that it is Al-Munshi'at meaning, "launched.''

[كَالاٌّعْلَـمِ]

(like A`lam.) This means, they are like mountains with their great size, and it also refers to the trade and commercial services they make possible, transporting cargo from one area to another and from one province to another. Ships provide various benefits for people, including transporting different types of goods they need. Therefore,

[فَبِأَىِّ ءَالاءِ رَبِّكُمَا تُكَذِّبَانِ ]

(Then which of the blessings of your Lord will you both deny)

[كُلُّ مَنْ عَلَيْهَا فَانٍ - وَيَبْقَى وَجْهُ رَبِّكَ ذُو الْجَلْـلِ وَالإِكْرَامِ فَبِأَىِّ ءَالاءِ رَبِّكُمَا تُكَذِّبَانِ ]

[يَسْأَلُهُ مَن فِى السَّمَـوَتِ وَالاٌّرْضِ كُلَّ يَوْمٍ هُوَ فِى شَأْنٍ فَبِأَىِّ ءَالاءِ رَبِّكُمَا تُكَذِّبَانِ ]

(26. Whatsoever is on it (the earth) will perish.) (27. And the Face of your Lord Dhul-Jalal wal-Ikram will remain forever.) (28. Then which of the blessings of your Lord will you both deny) (29. Whosoever is in the heavens and on the earth begs of Him. Every day He is (engaged) in some affair!) (30. Then which of the blessings of your Lord will you both deny)
