Chand dheaki k maslay per NASA ka jawab

Thank you. The above bring the following to my mind:

Do Islamic principles mandate using sighting by the naked (unaided) eye? Are there mandated requirements for healthy eyesight? Don't the Ruet-i-Hilal Committee use powerful binoculars and telescopes in addition to eyeglasses? If so, what prevents the use of such a long term calendar?

The words are (English translation)

‘Fast when you see it (i.e., the moon) and cease fasting when you see it, and if it is hidden or cloudy, complete the counting of Sha’bān as thirty days.’

It only implies actually seeing, it does not specify 'Unaided'. Any short-sigh person would need glasses, even that is also an aid because power lenses have magnification. There were no glasses or telescopes at the time of the Hadith and you physically see the object with your eyes when using a telescope.

Everyone knows that Galileo constructed the first telescope in 1610. It is also known that an English Franciscan Friar, Roger Bacon wrote about the scientific principles of corrective lenses in 1266. But to the best of my knowledge, the 'Inventor' of the eyeglasses has not been identified, what is known that spectacles were in use by the late 13th century, that is more than 600 years after the Holy Prophet (PBUH).

So the use of vision aids is not part of the original process of sighting the moon. But they are used now. So what prevents the next step of computational aids?

This is what the whole debate is about. I have already given my views on this matter in my first post. IMO there should be a dual approach. Use science to determine the location & time (where and when) to look but at least two persons must see it with their own eyes even if aided by the binoculars or a telescope.

Others Muslims are free to disagree with my views.
