What is the evidence for the permissibility of kissing a sister or the like, other than the evidence of mahram status? And did the Salaf kiss the hand or the like?

The questioner : So, is this the answer, O Shaykh? Is there no other answer and no other reasoning other than mahram status?

The Shaykh : From whom?

The questioner : Are there other texts regarding kissing a sister, kissing a mother?

The Shaykh : Nothing comes to mind right now; perhaps there are athar!

The questioner : Do you memorize or remember this athar: "That Abu Bakr (may Allah be pleased with him) used to kiss his daughter on her chest"?

The Shaykh : No, and how is it possible to kiss her on her chest?!

The questioner : This is what I was questioning!

The Shaykh : And where did you gather this from?

The questioner : We were discussing it like this, so the statement was presented without a chain of narration.

The Shaykh : I do not know him.

The questioner : Okay, O Shaykh, you say...

The Shaykh : May Allah have mercy on you.

The questioner : You said: It is not reported from the Salaf.

The Shaykh : You did not hear your companion!

The questioner : I said: May Allah have mercy on you.

The Shaykh : How is it that you have two tongues?

The questioner : No, I said it before you said it.

The Shaykh: Yes.

The questioner : I say: You mentioned what is reported from the Salaf about kissing the hand!

The Shaykh : Did I say it is not reported from the Salaf?

The questioner: Yes.

The Shaykh : Where is that?

The questioner : A little while ago.

The Shaykh: May Allah guide you.

The questioner : Or it was not reported in the Sunnah (the Prophet's way).

The Shaykh : I did not say that. Is your statement now absolute or restricted?

The questioner : No, it is absolute.

The Shaykh : And was your question absolute or restricted?

The questioner : It was restricted.

The Shaykh : May Allah forgive you, why do you mix the absolute and the restricted? I said kissing the mother's hand!

The questioner : Hmm, okay, excuse me.
