There is an evidence that heliocentrism was proposed by some ancient Greek philosophers, in particular Aristarchus of Samos. His work did not survive, and all we know about it is a brief mentioning in one work of Archimedes.

Concerning Ibn al-Haytham, Wikipedia mentions his works where he criticized Ptolemy, but does not mention that he ever advocated heliocentrism. If you have a source which says this, please give a reference.

It is highly unlikely that Copernicus could read Ibn al-Haytham. (I doubt that he could read Arabic and that al-Haytham was translated into Latin). But Copernicus mentions his ancient Greek predecessors.

Concerning "giving credit" this is a question of opinion. On my opinion, crediting Copernicus has nothing to do with "eurocentrism". (Aristarchus was also a European, and he is given some credit, though his work did not survive and we know almost nothing about it. About al-Haytham, I have never heard that he had a heliocentric system. Please give a source if you know one.)
