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.
This is the answer to their second objection. Obviously, there was no need to state that the restrictions about the Sabbath applied only to the Jews and had nothing to do with the law of Prophet Abraham (peace be upon him), because they themselves knew it. The restrictions were imposed upon the Jews because of their mischief and violations of the law. In order to understand fully the significance of this reference one is requested to read those passages of the Bible in which commandments about the Sabbath have been stated, e.g., Exodus 20: 8-11, 23: 12-13,31 : 1-17, 35: 23, and Numbers 15: 32-36. Besides this, one should also be acquainted with the impudent violations of the Sabbath. See Jeremiah:17: 21-27 and Ezekiel. 10: 18-24.
