May God bless you, highly respected sir, dear Dr. Shabbir Ahmed. I appreciate your help and time.
Excuse my questions if they took your precious time.
As my last question:
I learned from your posts that, in fact, a Muslim is one who believes in the Quran as the last scripture and the Exalted Prophet as the last messenger of God.
I once read in one of your posts that you said you have not seen many Muslims in your life.
Honestly, it confused me a bit, especially when I recall Allama Iqbal's last will that in which he called himself a Hanafi Sunni Muslim.
My humble questions:
According to the Quran, is a Sunni/Shia 'Muslim' a Muslim?
And can we apply those rules of the Quran about Muslims (e.g. marrying Muslims) to them?
