In ancient Israel, Sabbath-breakers were stoned to death (Exodus 31:14; 35:2; Numbers 15:32-36). Does this severe penalty show the importance of the Sabbath, that it is not just a ritual?
YUSUFALI: And remember We took your covenant and We raised above you (The towering height) of Mount (Sinai) : (Saying): "Hold firmly to what We have given you and bring (ever) to remembrance what is therein: Perchance ye may fear Allah."
YUSUFALI: But ye turned back thereafter: Had it not been for the Grace and Mercy of Allah to you, ye had surely been among the lost.
YUSUFALI: And well ye knew those amongst you who transgressed in the matter of the Sabbath: We said to them: "Be ye apes, despised and rejected."
YUSUFALI: So We made it an example to their own time and to their posterity, and a lesson to those who fear Allah.
Thus some of the Jews who transgressed in the Sabbath were put to death as per the Torah and transformed into Apes and Pigs in the Quran.
Thus the message is clear the Sabbath was great day for observance to the Jews and they knew how important it is to God. Some of them chose to challenge him and he killed some of them as in the Torah and turned some into Apes and Pigs in the Quran.
Thus it is not about the Jews, it is about disobedience to God. This can happen to any group of people who are not obeying God Muslims, Christians or Jews. In fact the hypocrite Muslims who would hesitate in their faith and cause break in the Muslim community God promised them to be the lowest in the hell fire in the day of judgment. Muslims when were not obedient over human history God would put above them leaders to oppress them and enemies to destroy and slaughter them. Thus the Just God of the Bible and the Quran takes the side of the righteous and obedient. in Many verses in the Quran God would elevate the Jews. The best of the people in this world are the prophets and most of them were Jews/Hebrew and Muslims love them.
Do you really still think that the Quran is Anti-Semitic. It is like me praise the Jews who work for human justice and progress of humanity and criticise the other Jews who care only about collecting money and care only about themselves.
