is our sadaqa accepted if we gave our sadaqa to professional beggers?

we live in a society where we have some time no idea about actually needy people and gave our sadaqa to some time professionl beggers as my concern I gave them my sadaqa to any begger because of reminding the quote of HAZRAT imam HUSSAIN(A.S) comes in my mind that "the needy ones lose their respect by asking you so do not lose your self respect by denying them" so some time it really confuse me that em i doing right or wrong
