Does one who uses the miswak while the imam is delivering the Friday sermon be considered to have invalidated his prayer?

Question:
He says: Honorable Shaykh, may Allah grant you success, if one uses the miswak while the imam is delivering the sermon, is he considered to have invalidated it?

Answer:
Yes. This is movement. The one who is listening does not move and does not speak. If he moves, or draws lines on the ground, or this is playing with pebbles, meaning he moves the earth and draws in the earth, then he has invalidated it. Yes.
