Mu'adh ibn Jabal رضي الله عنه reports that RasulAllah ﷺ said: 'When tribulations (fitan) arise or innovations, and a scholar does not reveal his knowledge; then the curse of Allah, the angels and mankind is upon him. Allah neither accept his obligatory acts nor his supererogatory.' [Kanz al-Úmmal, 1:179, Lisan al-Mizan, 5:911]. #Alahazrat commentates: 'When a misguided innovator - be he rafidi or mirzayi, wahabi or deobandi, and others; may Allah disappoint them all - seeks to misguide Muslims and creates discord and tribulation, then refuting him and removing doubts of Satan from the hearts of Muslims is the greatest obligation (farz e aáżam) and whoever stops from this (act of refutation) is included in, 'who turn others away from the path of Allah and try to make it appear crooked (Qur'an, 7:45). It is obligatory (farz) upon Muslims to not lend an ear to such misguided people (gumrāh) and misguiders (gumrāh gar). It is obligatory upon them to destroy the fitnah of rafidis and mirzayis and the khilafat committee. Where there is need for speeches of ulama, do them. If there is need to publish monographs, publish them. According to capacity, it is obligatory upon Muslims to spend money on this great obligation (farz e áżīm). When there is such a curse upon those who do not refute such heretics, then what about that impure one (khabīth) who stops from refuting them - what a severe anger and greatest curse (lánat e akbar) will he get? 'Those who are bent on wrongdoing will in time come to know how evil a turn their destinies are bound to take' (Qur'an, 26:227) [Fatawa Ridawiyyah, 9:286]
