tena tukaifuta ishara ya usiku, na tukaifanya ishara ya mchana ni yenye mwangaza ili mtafute fadhila itokayo kwa mola wenu mlezi, na mpate kujua idadi ya miaka na hisabu.
the night is invisible and the day is visible so that you may seek favors from your lord and determine the number of years and mark the passing of time.

na tumefanya usiku na mchana kuwa ishara mbili. tena tukaifuta ishara ya usiku, na tukaifanya ishara ya mchana ni yenye mwangaza ili mtafute fadhila itokayo kwa mola wenu mlezi, na mpate kujua idadi ya miaka na hisabu.
and we created the night and the day as two signs – we therefore kept the sign of the night indistinct, and the sign of the day visible – so that you may seek the munificence of your lord, and know the calculation of the years, and the accounting; and we have explained all things in detail, distinctively.
