What is the ruling on some of the brothers, who manage a shop affiliated with a mosque that was purchased in the Netherlands, taking a weekly sum of money for themselves without the knowledge of the other shareholders in the purchase of the mosque, and then later agreeing to this action?

If all shareholders bought the mosque building and the adjacent shop with the intention of making them a waqf (endowment), then no one is permitted to take from the shop's revenue if its endowment was specifically for the mosque's expenses.

However, if they endowed only the mosque without the shop, then it is permissible for anyone who did not endow their share of the shop to take from its revenue in proportion to their share.

It is permissible for whoever is responsible for developing and investing the endowment to receive a wage for their work, whether they are among the shareholders or not.

And if the brothers did not endow their share of the shop, or if they endowed it but then worked to develop it, then there is no impediment for them to take their share of the revenue or a wage for their work.
