فَلَمَّا بَلَغَا مَجْمَعَ بَيْنِهِمَا نَسِيَا حُوْتَهُمَا فَاتَّخَذَ سَبِيْلَهٗ فِى الْبَحْرِ سَرَبًا

Falammā balagā majma‘a bainihimā nasiyā ḥūtahumā fattakhaża sabīlahū fil-baḥri sarabā(n).

"But when they reached the junction between them, they forgot their fish, and it took its course into the sea, slipping away."
