What is the ruling on greeting with a hand gesture, especially when one is in his car?

A message was received for the program from one of the brothers, Hamud Fahd al-Hudhal from al-Aflaj. Our brother asks: What is the ruling on greeting with the hand, as is observed among many people, especially when one of them is in his car?
Answer: Greeting with a hand gesture is permissible when at a distance, or when the person being greeted cannot hear. However, one should combine it with verbal greeting, saying the greeting and gesturing. The Prophet (peace and blessings be upon him) once passed by some women and greeted them, gesturing with his hand to make it clear to them that he was greeting them, may Allah’s peace and blessings be upon him. So if the person being greeted is far away, or cannot hear the greeting due to a hearing impairment or other reasons, one should greet verbally and gesture so that the person understands that he is being greeted; there is no harm in that. However, relying solely on the gesture is not allowed; one should not rely on the gesture alone, because this involves imitating the enemies of Allah. Yes.
