I was curious whether there is really a Hadith about the destruction of Arabs. If not then we would like to sue for banning this person.
The matter of fact is that I prefer conservative things. Yours are not conservative. So I am considerably suspicious of you. After you present the Hadith I shall wait for brothers to verify your veracity. And if they do not come up with verification or refutation then I shall assume that your claims are not serious enough for them and hence these are not serious enough for me. So you will be justified in assuming that I am not one of those who are suitable impressed by your assertions. In other words you are not starting with a winning vibe, for me.
Al-Tirmidhi Hadith 5991 Narrated by Talhah ibn Malik Allah's Messenger (saws) said, "One of the signs of the approach of the Last Hour will be the destruction of the Arabs."
