The sadaqah which we generally take out for our safety, good things, etc.(excluding 12th Imam's sadaqah) , I know that it can be given to shia as well as non-shia. But my question is, Does 'shia' mean Syeds also or it means only Khoja. Is is haram to give to syed or is it haram for them to accept the sunnat sadqah which we generally take out?

You can give to any shia (syed non Syed)
Please give preference to shia than non shia Muslim
