Question Summary:
Is it permissible to have Iftaar hosted by a Non-Muslim?

Question Detail:

Is it permissible to break your ramadan fast at an aftar hosted by a Non-Muslim? In our case, a Hindu family hosted an aftar at our local Islamic Center for the Muslim Community. We not only volunteered there but also had aftar there. Would the fast be valid? and if not what should we do?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
 
Being hosted by a Hindu family for iftaar does not invalidate the fast. We assume the invite was accepted based on some wisdom and the food was Halaal.
And Allah Knows Best.
