Praise be to Allah, the Lord of the Worlds; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions. The persons, who claim to be Mahdi, are numerous. All of them proclaim to be the real al-Mahdi including Mohammad from Jonpour (India). Their false claims are refuted by texts of Shari'a (Qur'an and Hadith) proving he has not yet appeared. He will come in the last period just before the descent of Christ. The followers of Mohammad Jonpuri are among the deviant sects who turned away from the true Muslim community.
Please refer to the Fatwa82108.
Allah knows best.
