As'salamu Alaikum dear brother,
Tell him I am not interested. If he wants to debate, then he should come here as he came the first time on his own. We'll discuss whatever he wants to discuss. And I can limit it to only me and him. Please tell him to cut all of the BS and come here and debate if he is honest. Otherwise, I am not interested at all.
Jazaka Allah Khayr, dear brother Omar.
Take care,
Osama Abdallah
