النَّحْلِ · 124

إِنَّمَا جُعِلَ ٱلسَّبۡتُ عَلَى ٱلَّذِينَ ٱخۡتَلَفُواْ فِيهِۚ وَإِنَّ رَبَّكَ لَيَحۡكُمُ بَيۡنَهُمۡ يَوۡمَ ٱلۡقِيَٰمَةِ فِيمَا كَانُواْ فِيهِ يَخۡتَلِفُونَ

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
