What is the manner of returning the greeting in this hadith (Gabriel came to me and said, "Indeed, Allah sends you His peace")?

The questioner : In the hadith itself, his saying (peace be upon him): So how is the return here in the case of the Messenger (peace and blessings be upon him)? And now there is no room for anyone to say, "Indeed, Allah sends you His peace," so how does he (peace and blessings be upon him) return it? Or when he said to Khadijah (may Allah be pleased with her) Is the answer known, or is it left unmentioned?

The Shaykh : No, the answer is not known, but we can bring you close to the answer: Is it obligatory to return every greeting?

The questioner : For us, yes.

The Shaykh : How?

The questioner : Peace be upon you. And he returns the peace upon you.

The Shaykh : No, not always.

The questioner : It is possible in prayer by gesture.

The Shaykh : No, this is not a return.

The questioner : A gesture.

The Shaykh : A gesture.

The questioner : Do you call a gesture a return?

The Shaykh : No, except figuratively .

The questioner : .

The Shaykh :, the return is saying "Peace be upon you" when you say "Peace be upon you." As for returning by gesture, this is a legislative provision to compensate for what this praying person misses of the return of the greeting commanded in the Noble Qur'an. In any case, your question is valid regarding human relations between people, but regarding the Lord of the Worlds, it is completely different. This question reminds me that in the early days of Islam, they used to say in the tashahhud "Peace be upon Allah, peace be upon Gabriel, peace be upon Michael", so he (peace be upon him) said and so on. I think I have clarified my answer: this is a specific ruling between Allah and His Prophet, and we do not know if there is an answer or not?
