1) Ibn al-Shatir's planetary models for longitude predictions are non-Ptolemaic to the extent that they are expressible as combinations of uniform circular motions. Hence they are not subject to the criticisms directed toward Ptolemy in ancient and medieval times. 2) Several of the models (except for their being geostatic) are identical with those of Copernicus, who lived a century and a half after his Arab predecessor. 3) In reducing the geometric models to numerical longitude tables both Ibn… 
Holding or Breaking with Ptolemy's Generalization: Considerations about the Motion of the Planetary Apsidal Lines in Medieval Islamic Astronomy
TLDR
In medieval Islamic astronomy, the Ptolemaic generalization in the case of the equality of the motions of the apogees remained untouchable, despite the notable development of planetary astronomy, in both theoretical and observational aspects, in the late Islamic period.
