Question?
Are astronomical observations and calculations acceptable for the commencement of Ramadhan etc?
Answer:
There is unanimity amongst the jurists of islam that it is not permissible to start Ramadhan with astronomical calculations.Nabi SAW said:”Start fasting when you sight the crescent and celebrate eid when you sight the crescent.” (Bukhari Shareef). therefore sighting of the moon is a pre-requisite for the commencement of Ramadhan and Shawwaal and the birth of the moon is not the criteria.
