Surah Saba, Verse 18
وَجَعَلْنَا بَيْنَهُمْ وَبَيْنَ ٱلْقُرَى ٱلَّتِى بَٰرَكْنَا فِيهَا قُرًۭى ظَٰهِرَةًۭ وَقَدَّرْنَا فِيهَا ٱلسَّيْرَ ۖ سِيرُوا۟ فِيهَا لَيَالِىَ وَأَيَّامًا ءَامِنِينَ
Translation — Sahih International
And We placed between them and the cities which We had blessed [many] visible cities. And We determined between them the [distances of] journey, [saying], "Travel between them by night or day in safety."
