What is the ruling on combining raising the hand with the closing salam, or substituting it for the salam when at a distance?

However, combining raising the hand with the salam may be permissible at times and not permissible at others. If you are close and you say to the one greeting you, "Peace be upon you," then it is not permissible for you to raise your hand, because this raising is a sign of the non-Muslims.

The questioner : Even if whistling is used in a case of warning, such as danger.

The questioner : All...

The questioner : Absolutely, you answered absolutely.

The Shaykh : No, the question is not intended to be about prayer, it is clear, or substituting it for the salam when at a distance in prayer?

The questioner : ... .
