الكهف — Al-Kahf Ayat 60
وَاِذْ قَالَ مُوْسٰى لِفَتٰىهُ لَآ اَبْرَحُ حَتّٰٓى اَبْلُغَ مَجْمَعَ الْبَحْرَيْنِ اَوْ اَمْضِيَ حُقُبًا
Wa iż qāla mūsā lifatāhu lā abraḥu ḥattā abluga majma‘al-baḥraini au amḍiya ḥuqubā(n).
"And [mention] when Moses said to his servant, "I will not cease [traveling] until I reach the junction of the two seas or continue for a long period.""
