So you want to know some fact about Islam (for example is A equal to B). You decide based on severity of the question and the urgency, that an online fatwa site is the way to go. So you ask.
This will be how the typical reply seems to be composed.
Dear Brother / Sister in Islam,
We are very pleased/satisfied/impressed that you have chosen to further your knowledge of the deen and may Allah keep you always on the rightly guided path.
That is, of course, salutation. You expect that, and read on, wanting them to now answer your question. But the content will be slightly different.
To look at your question, is A = B, first we must understand where A and B are coming from. Before Islam, the root of the word A was from the A'ramic word 'Aaa'....
Now we look at historical contexts where A = D. Now D is slightly different from B, but we have the 2nd Caliph of the 4th Sultanate in the 1201 AD when ...
On and on ...
In the great work of Ahlan Wa Sahlan the great jurist Saqlain Al Karim has stated that A and Z are opposite in empirical terms ...
So we can conclude that a majority of the jurists are of the opinion D may be equal to E in some situations, while a minority of the ulema are of the opinion that D can never be equal to E.
As for A = B?
Allah and His Messenger Knows Best.
Seriously, while the Internet is great for research and expanding one's knowledge and quick lookups, I have had too many people telling, "Look! This is Islamic! Here's a fatwa site" (and from the link you can see they have followed the first Google link to some keyword searches). Is that Islamic? And second, why don't these Fatwas ever get straight to the point?
