Firstly lets look at christianity (the old testament should also be followed by christians as Jesus says in Matthew 5: 17-18 “Do not think that I [Jesus] have come to abolish the Law (the Old Testament) or the Prophets; I have not come to abolish them but to fulfill them. I tell you the truth, until heaven and earth disappear, not the smallest letter, not the least stroke or a pen, will by any means disappear from the Law (the Old Testament) until everything is accomplished.
Then Jesus said to the crowds and to his disciples: ‘The teachers of the law and the Pharisees sit in Moses’ seat. So you MUST OBEY THEM AND DO EVERYTHING THEY TELL YOU. But do not do what they do, for they do NOT PRACTICE what they preach.” (Matthew 23:1-3)”
From this we see Jesus says follow the Old testament, and the law of Moses.
Old Testament:
Deuteronomy 17:3-5 “And he should go and worship other gods and bow down to them or to the sun or the moon or all the army of the heavens, …..and you must STONE such one with stones and such one must DIE.”
2 Chronicles 15:13 “All who would not seek the LORD, the God of Israel, were to be put to death, whether small or great, man or woman
New Testament
Matthew 15:1-9
1 Then some Pharisees and teachers of the law came to Jesus from Jerusalem and asked,
2 “Why do your disciples break the tradition of the elders? They don’t wash their hands before they eat!”
3 Jesus replied, “And why do you break the command of God for the sake of your tradition?
4 For God said, ‘Honor your father and mother’ and ‘Anyone who curses his father or mother must be PUT TO DEATH.’
5 But you say that if a man says to his father or mother, ‘Whatever help you might otherwise have received from me is a gift devoted to God,’
6 he is not to ‘honor his father’ with it. Thus you nullify the word of God for the sake of your tradition.
7 You hypocrites! Isaiah was right when he prophesied about you:
8 ” ‘These people honor me with their lips, but their hearts are far from me.
9 They worship me in vain; their teachings are but rules taught by men.’”
Romans 1: 20-32 – Although they know God’s righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them.”
The Last and Final Testament ( The Quran)
The Quran says “there is no compulsion in religion” the quran also say in surah kaafiroon “to you is your religion to me is mine”.
