Now it's very easy to assume that those books, because they were from a library called Bait al-Hikma, were Muslim books, but that's not the case because the caliph that built that library, his name was al-Ma'mun, he was Harun al-Rashid's son.
Ahora bien, es fácil suponer que esos libros, que eran de una biblioteca llamada Al-Hikma eran libros musulmanes, sin embrago no es el caso porque el califa que construyó la biblioteca, su nombre era Al-Ma'mun era el hijo de Harun al-Rashid.
