Prophet Mohamed PBUH “Give to the one whose door is nearest to you”(Bukhari)You should never put your nationality over Islam
Meaning give Sadaqah(charity) to the people closest to you who need it.
Then and only then can you help somebody else but if your neighbor is in need it’s an obligation by Allah for you to help them first:
“He is not a true believer who eats his full while his neighbor is hungry”.
(Bayhaqi)
