(0:01) Presenter: The question that is repeatedly asked is regarding the permissibility of openly doing Inkaar (criticism) of the Imams (Muslim leaders) in front of the general public or openly?
(0:12) Shaikh Abdul Muhsin Al-Abbad Al-Badr: “If no harm results from it, there is no objection. That is, if one witnesses something objectionable, they should clarify it (0:20). They should clarify this objectionable matter because when the wrong becomes apparent, denouncing it also becomes apparent as a consequence of the wrong’s manifestation (0:41).”
Presenter: There are those who say that there is a distinction between giving advice to rulers (Naseehah) and denouncing what is wrong (Inkar-ul-Munkar), say that it is Naseehah (advice) that should be given privately (0:49). As for the first matter, it is known that if something wrong is done publicly, then it should be criticized publicly (0:55), using Abu Sa’eed Al-Khudri’s action as an evidence (0:58).
Shaikh Abdul Muhsin Al-Abbad Al-Badr: Undoubtedly, giving advice in private and writing to them or contacting them (1:04) is without doubt beneficial, and its benefit will be achieved by Allah’s permission (1:11). However, if something wrong occurs and people witness it, remaining silent about the wrong essentially means accepting it [the evil] (1:23) and failing to denounce it. Thus, denouncing it and explaining that it is impermissible is similar to what occurred with Abu Sa’eed Al-Khudri.
