Hazrat Mahdi (pbuh) will invite people to Islam from which they have deviated

ADNAN OKTAR: "When our Qaim Muhammad Mahdi (pbuh) appears, he will invite people to Islam.” When he appears, “he will lead people on the true path to Islam, from which they have deviated. He is named Mahdi (pbuh) as he leads people on the true path to Islam from which they have deviated. Since he will appear to administer the justice, he is called Qaim Muhammad Mahdi (pbuh)." (Kashf ul-Ghumma, volume 3, page 254, Irshad al-Mufid, page 343.)
