Does the prohibition include gesturing with the hand to silence a speaker during the Friday sermon?

Question:
Does gesturing with the hand to silence someone who is speaking, without using words, fall under the prohibition?

Answer:
Yes, he should not move. Gesturing is movement, and gesturing is movement. The Prophet (peace and blessings be upon him) said: meaning that touching pebbles is movement. So he should not move and he should not speak, but rather he should listen. He should listen, refraining from speech, cutting off his speech and his movement, and devoting himself to listening to the sermon.
