The purpose of Ibn al-Haytham in his article : "on suspicion of Ptolemy" is to raise doubts and objections and uncover the errors and contradictions of the astronomer and mathematician Ptolemy who lived in the second century in the main writings "Al-Majastti" and "El Iqtissas" and “El-Manadhir" which represents the scientific belief and the finest experimental research in the ancient world. This article serves as an epistemological and systematic warning to scientists to adhere to and think about old thought. This is the El Haytham’s critical philosophy that founded a new scientific model.
