Is it permissible to hang a prayer times board in the mosque that contains the name of a person and his place of work in a usurious bank?

There is no harm in hanging a prayer calendar in the mosque, even if the person who printed it works in a usurious bank and has written his name and workplace on it. The name of the usurious bank can be removed from the calendar by erasing or obliterating it. However, it is better to replace it with another calendar to distance it further from the suspicion of advertising for a usurious bank and from people taking the matter of usury lightly.
