What is the ruling on a man kissing another man, and when is kissing prescribed?

The questioner : Kissing hands!

Another questioner : What is the ruling on kissing, my Shaykh?

The Shaykh : Who is asking? Who is asking?

The questioner : A man kissing another man.

The Shaykh : Kissing a man's hand?

The questioner : No, a man kissing [another] man.

The Shaykh : Ah, it is not established in the Sunnah for a man to kiss another man when they meet and greet, except for kissing the hand of a scholar and a righteous person from among the people of knowledge only. As for kissing any part of the body for the general public when they meet one another, nothing authentic has been reported that serves as a proof for this. However, if we set aside this general case, we then enter into the specific cases, such as a man kissing his daughter, or his father, or his daughter or the like. This is found in the Sunnah. However, just as it is not permissible to mix this matter with the first matter, if it is permissible, for example, for a father to kiss his son or daughter on the head or cheek or the like, we do not transfer this to the first point, which is the general and comprehensive case. Likewise, it is not befitting to transfer the specific case of kissing the hand of a righteous scholar to, for example, a son kissing his father's or mother's hand, for this has also never been transmitted in the Sunnah. One should adhere to the limits in these matters, because the Prophet (peace and blessings be upon him) was asked, and it was said to him: "One of us meets his brother, should he bow to him?" He said: . He said: "Should he kiss him?" He said: . He said: "Should he shake his hand?" He said: .
In the safety of Allah.

The questioner: Peace be upon you.

The Shaykh : And upon you be peace, the mercy of Allah, and His blessings. The detail has become clear in this area.
