Alzheimer's Society Summer Quiz

I have finished all the ditloids apart from one which I am unsure of. The one I am struggling with is [glow=red,2,300]6th C=MK[/glow]

I've seen that the droid suggests it may be when Mohammed was killed but that was in 632 AD which is in the 7th century.

Unless the questionmaster has made a mistake of course...

I bet the person who set the question thinks 632 is the 6th century. Many people would think the same thing I guess.
