There you go, not entirely unexpected, but you're unable to give even a straightforward simple yes or no answer to a straightforward easy question. You had to qualify your answer with "if you know the facts". Which implies that if I do not know the facts then I am not sinful.
So let me clarify that no, I do not know the facts, and I'm definitely not going to take the word of some random person online.
In fact, the position of righteous Ulama is ALWAYS a valid position for the layman. Once I've determined that they are righteous scholars I do not need to ask them even a single question on the basis of their rulings. If you think that these righteous Ulama are like Mirza Ghulam Ahmed then we can pursue a separate discussion on that front, after you've been finally able give a simple straightforward answer to my original simple question.
I'm in the category of the vast majority of the layman in the country. I, like most other layman, have no idea about the processes involved in moonsighting in Saudi or any other country for that matter. I, like most other layman, have no idea on how my local Ulama come to the conclusion on how to decide the month, or which country to follow. I, like most other layman, hardly even know the names of the Islamic months, etc. etc.
Treat me like the vast majority of laymen in this country who simply follow what their local righteous Ulama are doing.
So once you know that I'm in the category of the vast majority of layman in this country, please try (for once) give a straightforward yes or no answer to the question posed before.
I'll capitalize the question (with further clarification in brackets) to make the seemingly difficult task easier for you:
AM I (LIKE THE VAST MAJORITY OF LAYMEN IN THIS COUNTRY) SINFUL FOR SIMPLY TRUSTING MY LOCAL RIGHTEOUS ULAMA ON WHEN TO START THE MONTH AND NOT ASKING THEM ANY QUESTIONS ON THIS ISSUE?
I await (with baited breath) a simple yes or no answer (without qualification pleeeeaaaaaassse)(for once)(for the third time!).
