Is it permissible to work as a Sharia auditor for the Sharia board of an Islamic bank, given that the applicant believes the fatwas of the bank's Sharia board contradict the fatwas of Fiqh academies and senior scholars' bodies?

There is no objection to working as a Sharia auditor in a bank to monitor the adherence of its management and branches to the regulations of the bank's Sharia board, provided that the board is not known for being lenient or frequently violating the decisions of Fiqh academies and the fatwas of prominent scholars. If the board's decisions tend towards leniency or circumvention of established rulings, then this work must be avoided. However, if the disagreement is over matters where disagreement is permissible, then there is no objection to the work.
