For all the people wavering as to whether to follow Saudi or not. Here's a recipe:
For the next 12 months find out after the start of the month....
1:When Indians sight the moon
2:When Pakistanis sight the moon
3:When South Africans sight the moon
4:When the Saudis sight the moon
It is well known in the South Asian community that 1, 2 & 3 ALWAYS sight the moon with regards to Sharii principles.
I have been doing this for many years.....and it is beyond a my simplistic understanding as to how Saudi ALWAYS sight the moon atleast 1 day and more commonly 2 days ahead of other known sightings. Basic Geography and Astronomy will tell you that there should be atleast some months in the year where our Indian and Pakistani brothers should see the moon on the same night as the Saudis. The same being true for our South African cousins.
The other point worthy of note is that Moon sighting predictions ala http://www.moonsighting.com are almost always correct with regards to countries 1, 2 & 3.
It is a relatively straighforward test, which over the course of 12 months will inject serious misgivings with the Saudi sightings. All this WITHOUT a scientist in sight.
The only answer for the above is that "there is a pre-screening of the new moon witch is reserved for Saudis only... followed by a general release a day or two after"
My 2 pennies worth.
May Allah make this Ramadhan a prosperous one for us all.
