Just kidding.
You let it dry because the water/solvent can greatly affect the MP of the compound.
You want as pure a sample as possible.

As a side note.......one time we had to rush a recrystallization where we didn't have time to let the recystallized compound dry....
We got a yield of about 200% and a ridiculously wrong MP measurement.
LOL.
