Sura Sabaʾ 34:18

وَجَعَلْنَا بَيْنَهُمْ وَبَيْنَ ٱلْقُرَى ٱلَّتِى بَٰرَكْنَا فِيهَا قُرًى ظَٰهِرَةً وَقَدَّرْنَا فِيهَا ٱلسَّيْرَ سِيرُوا۟ فِيهَا لَيَالِىَ وَأَيَّامًا ءَامِنِينَ

wa-jaʿalnā baynahum wa-bayna l-qurā allatī bāraknā fīhā quran ẓāhiratan wa-qaddarnā fīhā l-sayra sīrū fīhā layāliya wa-ayyāman āminīna

Between them and the Cities on which We had poured our blessings, We had placed Cities in prominent positions, and between them We had appointed stages of journey in due proportion: "Travel therein, secure, by night and by day."
