I want to raise money to open up a community well through the charity 'Muslim hands' as sadqa for my father who recently passed away. I was thinking of using the site 'Just giving' where others can contribute. The money goes directly to Muslim hands. The only part I'm confused about is how are Muslim hands going to know I want them to make a community well for sadqa and the money raised is not for any of the other charities they do, for example donating to Gaza.
