The role of a Salafi Imām in a masjid run by dodgy admins

Question posed to Sheikh Yaḥyā ḥafidhahullāh Question: We have a Masjid where the administration is not Salafi but the Imām is. The administration invites people (to deliver classes/lectures) whose conditions are unknown. Does the Imām stand by and listen to them give their talks knowing their conditions are anonymous? Answer: I advice to leave off these administrations in the Masājid, for verily it is a newly invented matter (innovation). It did not exist in the time of the Salaf, may Allāh be pleased with them all. Adversely you’ll find this matter in the lands of the Muslims, as well as here in Yemen. You’ll find they say the administration is so and so or a certain group of people. They may even reach a point where they have an election for the purpose of reforming the administration. This is one issue, the second issue is as long as the Masjid is not under the control of the Imām and he is merely as an Imām of the Masjid (teaches, leads the prayers, gives the Khutbah, connects them to the people of Knowledge, etc.), while he disapproves that which he sees according to his ability, as it comes in the well known Narration: The Prophet, may the peace and prayer be upon him, said, “Whoever sees an evil he should change it with his hands and if he is not able then with his tongue (he should speak about it) and if he is not able then he should hate it in his heart and this is the weakest of Faith.” Recorded by Imaam Muslim in his Saheeh narrated by Abu Sa’eed Al-Khudri. And he does so whether he sees an evil from the people of innovation that attend the Masjid or other than that which occurs from immorality that he is able to change. But if he is unable to change any of the evils, then it is advised that he stays away in this situation, for verily he is a witness to evil and he is not able to change it. Allah ﷻ says; وَٱلَّذِينَ لَا يَشْهَدُونَ ٱلزُّورَ وَإِذَا مَرُّوا۟ بِٱللَّغْوِ مَرُّوا۟ كِرَامًۭا “And those who do not witness (attend, speak) falsehood, lies and if they pass by some false speech, they pass by it with dignity (not exposing themselves to its harms and not being entertained by staying away from it).” Al-Furqaan: 72 If he is able to go to another Masjid and establish The Call to As-Salafiyyah there, then that would be better for him. Thus, this affair is one of two circumstances; either the Imām has the ability to change the evils that occur in this Masjid, from the way of the people of innovation, then he remains and makes changes according to his ability. Or either he does not have the ability to change any of the evils and he witnesses them, in which case he must leave for another Masjid as we have mentioned.
