Wasif Ali Wasif has said well

If it is decided that
May Allah Almighty take all these people to Paradise, this is our journey, this will be with us there too. Then there will be no quarrel

The quarrel happens then,
When man allocates paradise for himself, and calls another hell, then there is strife
So, you let the other one go to heaven too, where you are going.
Then there will be no quarrel.
Pray for him too, then there will be no quarrel
The quarrelsome one, quarrelsomely, quarrelsomely, unknowingly, quarrelsomely, otherwise quarrelsome.
Small knowledge quarrels and those with great knowledge do not quarrel. Whoever understands, there will be no quarrel

Then the quarrel ends
Whoever saw something, the quarrel ended.
And he who does not know keeps arguing that this is, that is, here it is, there it is. He has arguments and quarrels.
Allah Almighty repeatedly said that you should not do mischief. When there was a dialogue with the angels, the angels said that you are creating a human being who is "min yafsad wa yafsak al-damaa".

So Allah Almighty said

The point is, "I know, I don't know." I know what you do not know. And I know this is very good.

Evil is in him who quarrels. It was the opinion of the angels that man would quarrel, but Allah Almighty was sure that he would not quarrel.
So, whoever leaves the quarrel, he has fulfilled the trust of Allah Almighty.
And, the one who is arguing has established the trust of the angels

Now it's your turn to think for yourself that he's arguing. But do not argue

It was a miracle of the Holy Prophet that a man came to him with a sword to quarrel and he said not to quarrel and said, "Peace be upon you." Then, where do the swords live .

The word was read and finished
The only morality is not to quarrel.
So do not quarrel, but treat him with love. Inshallah the problem will be solved.
