Where allegiance will be sworn to Hazrat Mahdi (as)

They will find him at the Corner in Mecca and say: "If you do not accept our oaths of allegiance, if you do not protect us against the army of the Sufyan, which is seeking us and has one from Haddam at its head, then may our sins be upon you and our blood on your head.” At this, Hazrat Mahdi (as) will sit between the Rock and the Pillar, and he will extend his hand and accept their oaths.” (Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, p. 39-40)

Allegiance will be sworn to him between the Rock and the Pillar. Hazrat Mahdi (as) will be so compassionate that in his day, nobody will be woken from his sleep, and nobody’s nose will be made to bleed.” (Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-MuntadharAl-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, p. 42)

Three or seven days, after you see a fire from the east, expect to see the appearance of line of Muhammad, a herald from the sky will call out the name of Hazrat Mahdi (as), and everyone in East and West will hear that voice. (Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 32)

When innocent people are killed and his brother is killed in Mecca, a voice will cry out from the skies: “This is your command. This is the Mahdi (as), who will fill the world with justice.” (Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 35)

Widespread strife that seems unlikely to ever end will arise and last until the cry “The Mahdi is the leader, that is the truth” is heard three times from the skies. (Ibn Hajar al-Haythami, Al-Qawl al-Mukhtasar fi `Alamat al-Mahdi al-Muntadhar, p. 55)

It is noted in the hadiths that a voice from the sky will tell the news of the coming of Hazrat Mahdi (as), in other words, that everyone will hear these glad tidings over the radio and television. We are told this voice will reach everyone in the East and West. It is even revealed that everyone will hear this voice in his own language:

There will be a voice from the sky to the people of the earth, such that everyone will hear it in his own language. (Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir az-Zaman, p. 37)

News reports reach just about everyone in their own countries, translated into the language of that country, via radio, television and the Internet. People will be told of the coming of Hazrat Mahdi (as) in the same way.
