Is selling merchandise and receiving its price in the mosque considered among the forbidden transactions?

Paying off a debt inside the mosque is not considered among the prohibited forms of selling, as it differs from selling in terms of bargaining, give-and-take, and contracting. It is permissible to pay off a debt therein, especially if it is a small amount that does not require extensive counting or weighing. However, if it is a large amount that necessitates effort, weighing, and careful scrutiny, then it is disliked.
