It is not for a believing man or a believing woman, when Allah and His Messenger have decided a matter, that they should [thereafter] have any choice about their affair. And whoever disobeys Allah and His Messenger has certainly strayed into clear error. - Quran:Al-Ahzab 33:36 (islam)

-What will happen to you if you disobey?
- Are you then considered as a hypocrite (4:145), what will happen to you?

And who is more unjust than one who is reminded of the verses of his Lord; then he turns away from them? Indeed We, from the criminals, will take retribution. - Quran:As-Sajdah 32:22 (islam)

And they followed [instead] what the devils had recited during the reign of Solomon. It was not Solomon who disbelieved, but the devils disbelieved, teaching people magic and that which was revealed to the two angels at Babylon, Harut and Marut. But the two angels do not teach anyone unless they say, "We are a trial, so do not disbelieve [by practicing magic]." And [yet] they learn from them that by which they cause separation between a man and his wife. But they do not harm anyone through it except by permission of Allah. And the people learn what harms them and does not benefit them. But the Children of Israel certainly knew that whoever purchased the magic would not have in the Hereafter any share. And wretched is that for which they sold themselves, if they only knew. - Quran:Al-Baqarah 2:102 (islam)

O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you - then indeed, he is [one] of them. Indeed, Allah guides not the wrongdoing people. - Quran:Al-Ma'idah 5:51 (islam)

-If you take a Jew as guardian, you will be treated by Allah as a Jew, are you then going to Hell?
- What is a guardian, someone who help you?
- Do you have to refuse help from Jews and Christians?
- If you accept, do you need to curse them in your heart (Tafsir 3:28)?
