The astronomers and even some Ulama are saying that since there is absolutely no possibility of sighting the moon after the 29th this Sha'baan, search

Answer

It is not permissible to abstain from sighting the moon at the end of the 29th day of Sha'baan on the basis of astronomical calculations. This action is haraam. Rasulullah (sallallahu alayhi wasallam) had commanded the search for the hilaal at the end of the 29th day of every Islamic month. As far as Muslims are concerned, it is not an issue of whether there is the possibility of sighting or not, or whether the birth of the moon is only the next day. The issue is the command of Allah Ta'ala delivered to us by Rasulullah (sallallahu alayhi wasallam). Nabi-e-Kareem (sallallahu alayhi wasallam) commanded that we should search for the moon at the end of the 29th day. This is all we know and this is our only concern. The Ummah has absolutely no right to opt for the kufr of ignoring Rasulullah's command for the sake of adopting the bunkum of the astronomers and the miscreant, misguided ulama. It is Waajib to search for the moon at the end of the 29th day. Abandoning this Waajib Masnoon tenet of the Shariat is sinful and haraam.
