Sahih International
Allah alternates the night and the day. Indeed in that is a lesson for those who have vision.
Muhsin Khan
Allah causes the night and the day to succeed each other (i.e. if the day is gone, the night comes, and if the night is gone, the day comes, and so on). Truly, in these things is indeed a lesson for those who have insight.
Pickthall
Allah causeth the revolution of the day and the night. Lo! herein is indeed a lesson for those who see.
Yusuf Ali
It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision!
Shakir
Allah turns over the night and the day; most surely there is a lesson in this for those who have sight.
Dr. Ghali
Allah turns about (i.e., alternates) the night and the day-time. Surely in that is indeed a lesson for the ones endowed with beholdings.
