Salam brother Javaid,
I read your reply and find it as an honest strive to reach the truth. But I need to be clear on your point of view so can you please help.
You said that Dr Shabbir’s translation of Saum (please keep in mind I am not saying I agree with him 100%) is something that “should be” carried on 24/7 throughout the year and should not be specific to a month as mentioned in Quran and then you say that strengthening of character requires some kind of training… so one needs some kind of training that should be staying hungry and thirsty for specific periods during the day for a month and this is what saum is.
Do I understand right up to this point?
While I am writing the rest of my query can you check out this and tell what you think about that. http://www.quraniceducationandresearch.com/
