Khairaat and Sadaqa
Q:
1) I would like to know the difference between khairaat and sadaqa and to whom and when we can give these?
2) I have my pay around 440 USD, in which I send amount to my family. Do I have to give zakat on this?
3) For job purpose, I am living in another city of Pakistan. How can I serve my parents, as Islam says that we have to make "KHIDMAT" for our parents?
