A few years ago, I had raised money for construction of a Madressa. The money was raised from different sources. I came to find out that the Madressa was not built because there was a problem with the account. Now the problem is resolved. The jamaat has asked that these funds be used in the extension and renovation of the mosque. I do not remember the names of the donors so I am not able to ask them.
Please can you advise how to go about this?

You can use it only for Madresa
