If a mute person makes a gesture during his prayer that is understood by others, does his prayer become invalid?

Question:
If a mute person makes a gesture during his prayer that is understood by others, does his prayer become invalid?

Answer:
No, the prayer does not become invalid. If he gestures, the Prophet (peace and blessings be upon him) used to gesture during his prayer (peace and blessings be upon him) in a way that did not invalidate the prayer. If you gesture to a person who is wandering around to sit down, or gesture to him to stand up, or gesture to him to check the phone because he is looking at the phone, there is nothing wrong with it. The Prophet (peace and blessings be upon him), when people greeted him, would greet them back with a gesture. If you go back to the fact that a gesture takes the place of a gesture, this is a deviation.
