There is no such rule. They may place their hands and arms where ever they wish. If while doing so they make contact, you may have the option of calling a foul. However, I've never seen it called.

Camron is correct.
One of my pet peeves is when officials tell players not to do things that are legal. I frequently hear officials tell players to keep their hands/arms in their own spaces during FTs.
That is flat out wrong.
