The Ruling on Relying on Astronomical Calculations in the Sighting of the New Moons
Machine translationRead the Arabic original
Question:
The questioner Abu Sa'd says: What is the ruling in the Shari'ah, in your view, regarding astronomical calculations for the sighting of the new moons in our present time? Are they considered and acted upon?
Answer:
No, they are not acted upon; the sighting is what is acted upon. The Prophet (peace and blessings be upon him) said:Musannaf Ibn Abi Shaybah 3:154 for one day. So the practice is based on the sighting, not on astronomical calculations. Yes.

Answer:
No, they are not acted upon; the sighting is what is acted upon. The Prophet (peace and blessings be upon him) said:
Fast when you see it, and break your fast when you see it. If it is obscured from you, then estimate for it. In another narration: complete the number of Sha'ban as thirty days.
صوموا لرؤيته، وأفطروا لرؤيته، فإن غم عليكم فاقدروا له، وفي رواية فأكملوا عدة شعبان ثلاثين
