Severus Sebokht was a Syriac scholar and bishop who was born in Nisibis, Roman Syria in 575 and died in 667. Sebokht said and I quote:
I shall now speak of the knowledge of the Hindus of their subtle discoveries even more ingenious than those of the Greeks and Babylonians - of their rational system of mathematics or of their method of calculation which no word can praise strongly enough!

The first definite external reference to the Hindu numerals is a note by Severus Sebokht, a bishop who lived in Mesopotamia about 650. Since he speaks of “nine signs,” the zero seems to have been unknown to him. By the close of the 8th century, however, some astronomical tables of India are said to have been translated into Arabic at Baghdad, and in any case the numeral became known to Arabian scholars about this time. About 825 the mathematician al-Khwārizmī wrote a small book on the subject, and this was translated into Latin by Adelard of Bath (c. 1120) under the title of Liber algorismi de numero Indorum. The earliest European manuscript known to contain Hindu numerals was written in Spain in 976.

"Also according to modern skin color maps, Sindh doesn't fall under the label black skin, so the derogatory term Hindu as a black person doesn't apply to the people known today as Sindhis who were historically seen even by many invaders as an Aryan race of light skinned, tall stature people."
