What is the ruling on inviting preachers of falsehood to jointly invoke God's curse on the liars?

[Ibn Sina]

Here are the relevant verses regarding it:

الْحَقُّ مِن رَّبِّكَ فَلاَ تَكُن مِّن الْمُمْتَرِينَ

The Truth (comes) from Allah alone; so be not of those who doubt.

فَمَنْ حَآجَّكَ فِيهِ مِن بَعْدِ مَا جَاءكَ مِنَ الْعِلْمِ فَقُلْ تَعَالَوْاْ نَدْعُ أَبْنَاءنَا وَأَبْنَاءكُمْ وَنِسَاءنَا وَنِسَاءكُمْ وَأَنفُسَنَا وأَنفُسَكُمْ ثُمَّ نَبْتَهِلْ فَنَجْعَل لَّعْنَةُ اللّهِ عَلَى الْكَاذِبِينَ

If any one disputes in this matter with thee, now after (full) knowledge Hath come to thee, say: "Come! let us gather together,- our sons and your sons, our women and your women, ourselves and yourselves: Then let us earnestly pray, and invoke the curse of Allah on those who lie!"

[Al Imran: 60-61]

I don't understand. Could you clarify?
