Yesterday, I was thinking about Aamiin. I had the urge to be sure, and find out more about this word I'm uttering daily. Aamiin - this is how I'm going to spell it in roman letters from now on, or maybe just use the clearer Arabic word itself. In the past, I've always spelt it as Ameen. Now, I have just learnt the differences :-\.
Aamiin, In Arabic alphabets is spelled as آمين. with that longer sound at alif. Amiin ( أمين ), has a different meaning. It means ''honest or trustworthy' like Rasulullah SAW, was known as Al Amiin, the trustworthy. If it's just Amin (أمن), it means 'peace, secure'.
Whereas aamiin (آمين ), when I checked the Mawrid (المورد), it indicates the English word 'Amen'. I'm not surprised, I can understand how they mean the same thing - these people's original religion, is the one religion of the same God. So, anyway, Amen, in the English dictionary, shows the meaning to be 'so be it'. As in 'May God make it be.'
So, that's what I understand of Aamiin now.
Allahua'lam. الله أعلم (Allah knows best).
