16:124 · An-Nahl
إِنَّمَا جُعِلَ السَّبْتُ عَلَى الَّذِينَ اخْتَلَفُوا فِيهِ ۚ وَإِنَّ رَبَّكَ لَيَحْكُمُ بَيْنَهُمْ يَوْمَ الْقِيَامَةِ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ
The Sabbath was only made (strict) for those who disagreed (as to its observance); But Allah will judge between them on the Day of Judgment, as to their differences.
