If these are the traits of
the senior scholar as is mentioned in the question,
Bohras then he is not permitted to announce repudiation from those who object to what he commits of kinds of Shirk (associating others with Allah in His Divinity or worship). He should accept their advice and give up appointing himself as a deity and being described with attributes that are Allah's alone as Al-Uluhiyyah (Allah's Exclusive Right to be worshipped) and possession of hearts and souls. He should also stop asking his followers to worship him and to exaggerate in supplicating and surrendering to him and to members of his family. Moreover, those who object to what he commits of Shirk should repudiate him and his misguidance if he does not accept their advice by following the Qur'an and the Sunnah of the Prophet Muhammad (peace be upon him). They should also repudiate his followers and all those who are similar to them of Taghuts (false gods) and their worshippers. (Part No. 2; Page No. 389) Allah (Exalted be He) says:
And hold fast, all of you together, to the Rope of Allâh (i.e. this Qur’ân)
Indeed in the Messenger of Allâh (Muhammad صلى الله عليه وسلم) you have a good example to follow for him who hopes for (the Meeting with) Allâh and the Last Day, and remembers Allâh much.
And verily, We have sent among every Ummah (community, nation) a Messenger (proclaiming): “Worship Allâh (Alone), and avoid (or keep away from) Tâghût (all false deities i.e. do not worship Tâghût besides Allâh).”
Those who avoid At-Tâghût (false deities) by not worshipping them and turn to Allâh (in repentance), for them are glad tidings; so announce the good news to My slaves -
Those who listen to the Word [good advice Lâ ilâha illallâh - (none has the right to be worshipped but Allâh) and Islâmic Monotheism] and follow the best thereof (i.e. worship Allâh Alone, repent to Him and avoid Tâghût) those are (the ones) whom Allâh has guided and those are men of understanding.
Indeed there has been an excellent example for you in Ibrâhîm (Abraham) and those with him, when they said to their people: "Verily, we are free from you and whatever you worship besides Allâh: we have rejected you, and there has started between us and you hostility and hatred for ever until you believe in Allâh Alone"
to His saying:
Certainly, there has been in them an excellent example for you to follow - for those who look forward to (the Meeting with) Allâh and the Last Day. And whosoever turns away, then verily, Allâh is Rich (Free of all needs), Worthy of all Praise.
