Sheikh Ahmad Yasin Bursavi explains that Hazrat Mahdi (pbuh) is in Turkey.

SHEIKH AHMAD YASIN: Around the years 2024-2026, by the leave of Allah, you will all kiss the hands of Hazrat Mahdi (pbuh).  The Prophet Jesus (pbuh) will appear right after him. You will see, look, May Allah grant all of us to perform the prayer behind the Prophet Jesus (pbuh). But that day the trial gets harder. It gets very hard. That is because  no one wants Hazrat Mahdi (pbuh) to emerge. No one wants the Prophet Jesus (pbuh) to come. The guidance will be left to Hazrat Mahdi (pbuh), the religious orders (Tariqas) will come to an end. All ways will be exhausted. Today what we all do is preservation. It is to preserve the disciples and train them for Hazrat Mahdi (pbuh). It is to prepare them for him. We are approaching such a great day.

I know, I saw myself, if Allah grants insha'Allah. May Almighty Allah grant us the honor of performing the prayer behind him insha'Allah.

I will sit at the same table as Hazrat Mahdi (pbuh). I will say "my sultan, my commander." I will kiss his hands. I will receive his blessing. Could there be an honor greater than this?

SHEIKH AHMAD YASIN: Wake up; such a person is coming. Such a person is alive. This person is in our country. He is in our country. He is in your country. He is serving. Open your eyes, find him. Find him.. Hazrat Mahdi (pbuh) who is the owner of all these and also owner of me and who is my superior will come. I am preparing for him. Allah-u Akbar.
