Qur'anic reference to the Samarita

AAWW

If Allah swt Himself is the one who mentioned the encounter between Mousa PBAH and the Samaritan in the Quran, then what else we need to assure the authenticity of these historical information!?

As of the doubts people of different faiths might raise in this regard; we believe that the current (what so called) scriptures they refer to are not the original ones revealed by Allah swt, and that these books are man-made ones in most of their contents if not in their entirety. Consequently; whatever doubts or misconceptions they raise deriving from these books is basically invalid, with all due respect!
