Imam Jaffar bin Muhammed (as) was the grandson of Hazrat Hussein. Under his other name of Imam Jaffar Sadik he provided much important information about Hazrat Mahdi (as) and said that people all over the world would be able to listen to statements made by Hazrat Mahdi (as) in the light of verses of the Qur’an and the hadiths of our Prophet (saas). It is even clear from this statement by Imam Jaffar Sadik that people will make use of developing communications technology in listening to Hazrat Mahdi (as). Because, as Jaffar Sadik says, in order for people to be able to listen to Hazrat Mahdi (as) they must make use of internet technology and his words must be translated simultaneously into their own languages over television and the internet. In this way, people all over the world will be able to listen to Hazrat Mahdi (as) in their own languages. (Allah knows the truth)
