It is related that Muḥammad said, “Let none but three classes of people cross the sea (for it has fire under it which causes its troubled motion), namely, (1) those who perform the Ḥajj, or ‘Pilgrimage’; (2) those who make the ʿumrah, or ‘visitation’; (3) those who go forth to war.” (Majmaʿu ʾl-Biḥār, vol. i. p. 76.)
The following are the names of the seas as current in Muḥammadan literature:—
Al-Baḥru ʾl-Ak͟hẓar, the Green or Indian Ocean.
Al-Baḥru ʾl-Abyaẓ, the White or Mediterranean Sea.
Al-Baḥru ʾl-Aswad, the Black, or Euxine Sea.
Al-Baḥru ʾl-Azraq, the Blue or Persian Sea.
Al-Baḥru ʾl-Qulzum, or al-Baḥru ʾl-Aḥmar, the Red Sea.
Al-Baḥru ʾl-Lūt̤, the Sea of Lot or Dead Sea.
Al-Baḥru ʾl-K͟hiẓr, the sea of Khizr, the Caspian Sea.
