As there are so many Mohammeds, it would be appear to be the name of choice in Islam, are they known by another more familiar name by family and friends?
I'm seriously not being ignorant nor obtuse here but surely all the Mohammeds and all the spelling variations must be referred to with a different name within their family circles.
It would be impossible to shout for Mohammed...you'd get an entire street at your door !
