Surah 34 : Ayah 18

وَجَعَلْنَا بَيْنَهُمْ وَبَيْنَ ٱلْقُرَى ٱلَّتِى بَـٰرَكْنَا فِيهَا قُرًى ظَـٰهِرَةً وَقَدَّرْنَا فِيهَا ٱلسَّيْرَ ۖ سِيرُوا۟ فِيهَا لَيَالِىَ وَأَيَّامًا ءَامِنِينَ

We placed [a chain of] towns between them and the towns We had blessed[12], and We made between them well-measured distances[13]: “Travel through them by night and day safely.”
