[ 4:140] He has instructed you in the scripture that: if you hear GOD’s revelations being mocked and ridiculed, you shall not sit with them, unless they delve into another subject. Otherwise, you will be as guilty as they are. GOD will gather the hypocrites and the disbelievers together in Hell.
This verse tells us that Submission is a religion of peace. Imagine if someone is mocking someone you love like your parents, spouse or children? Most people would retaliate. Since believers love God the most, God is telling us that in such a scenario the proper response is to get up and leave.
Freedom of Speech
Respect for the Word of God
6:68 If you see those who mock our revelations, you shall avoid them until they delve into another subject. If the devil causes you to forget, then, as soon as you remember, do not sit with such evil people.
6:69 The righteous are not responsible for the utterances of those people, but it may help to remind them; perhaps they may be saved.
88:21 You shall remind, for your mission is to deliver this reminder.
