Thanks for the explanation bro and is Ahad only means one when you look up Arabic dictionary ? And why Allah said Allah is Ahad not Allah is wahid in Al-Ikhlas ?
Can you please watch this video, the video have been translated into Indonesian and many Christian channel have publish this with Indonesian translation. The video have become popular among the Christian in Indonesia since the beginning of this year. And he has many videos, not only one but this video specifically use Arabic as a basis of his argument so I ask for your help.
I hope you can counter his argument based on Arabic language and posted in here and I will try to translate it into Indonesia and post it to that channel. If you have time you can also post your comment on this channel since many Indonesian also understand English so you can debate them directly.
