Sabbath

While the Sabbath is not obligatory upon the followers of the Quran, it was a commandment for the upholders of the Torah. The Sabbath was to be upheld on the seventh day of the week, and interestingly, this word occurs in the Quran precisely seven times as well.

Sana & ʿām

The Quran uses two different words for year: “ sanah” ( سنة) and “ʿām” ( عام). This shows that there are two different systems for determining the year according to the Quran. The difference between these two terms is that “ sanah” ( سنة) is in reference to the solar year, while “ʿām” ( عام) is in reference to the lunar year.
