Suppose someone gives sadaqah jariya (ongoing charity) like for a free education program building. This building is going to be built in the next 2 years.
But anyone can give sadaqah for construction of that building right away. Is that considered as sadaqah for those 2 years? I ask because the actual use of the building will take place after construction is completed (in 2 years).
Will that sadaqah be effective for those 2 years i.e. during the period of construction?
