The times of lunar and solar eclipses are known through calculation of the planet movements by which we can know whether it is full or partial. There is nothing strange regarding this because it is not of the Ghayb (the Unseen) matters (Part No. 1; Page No. 635) for everyone but it is not known by those who do not have the knowledge of calculating the planet movements. It is not considered a matter of Ghayb for those who have the knowledge of this science because they can figure it out through regular causes known through the study of this science. It does not contradict the fact that lunar and solar eclipses are signs of Allah by which He frightens His servants to go back to their Lord and obey Him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
