Violence and anarchy in society and PKK terror will appear during Hazrat Mahdi's (as) occultation
Hazrat Mahdi (as) will not appear much in public at one specific period in his life; he will meet with very few people
We understand from the hadiths that the Mahdi’s time when he kept a low profile out of the public view has probably passed. However, there can still be another similar era and a great cleansing at the last moment.
The Mahdi’s disappearance twice mentioned in the hadiths probably refers to his imprisonment twice.
Mahdi (pbuh) is explained in a concealed manner in Surah Al-Qahf, in Surah Yusuf, in the story of the Prophet Solomon (pbuh), in the 55th verse of Surat An-Nur and in many other verses of the Qur’an. In fact this is a characteristic of Mahdi (pbuh); he is the concealed one.
The year 1986 is the year that Hazrat Mahdi (pbuh) will enter an environment of hardship and that he will dissapear from the sight of people.
Hazrat Mahdi (as) will be now and again arrested due to the baseness of disbelievers. And he will be hidden sometimes. Otherwise he is not someone who will hide in the cave for a thousand years. This is rubbish.
