Re: Deciding on the Moon
If you are on moon (like astronaut), how do you know if the next day is Eid? Because you are seeing moon all the time.
Is it haram to visit moon in ramzan.
OOPS. sorry for posting this question a 300 years earlier.
Peace Robert
It is good that you have realised that the question is not relevant, but may be so in 300 years.
There is always a way out in fiqh that is why Islam has come to us. Perhaps, in those days if people are living on the moon, they would be made to calculate their months rather than view the moon, however, there may be a possibility to look for the Earth crescent instead of the moon one, a more fundamental problem would be which direction would the moon dwellers pray, the obvious answer to this is towards the Earth, but that will not be adequate because the Earth will keep moving, a way out answer could be that another Qiblah for the moon be built another House of God on the moon towards which all moon dwellers would pray.
You see it is not the phsyical aspect of the ritual that is important it is the spirit behind the action. All of these answers are hypothetical based on a hypothetical question I'm no scholar and my answers should not be taken as scholarly however you are indeed expecting such replies if that is your questions are not seen as inanities or taunts.
