Ruling 2709

If some property is endowed for repairing a mosque but the mosque does not need any repairs and neither is it expected that it will need some repair work in the not too distant future, and if it is not possible to collect the income from the property and keep it so that it can be spent on repairing the mosque later on, then in such a case, the obligatory precaution is that the income from the property must be spent on a cause that is close to what the endower had in mind, such as securing items that are required by the mosque or repairing another mosque.
