Assalaamu alaykum. I hope this email finds the shaykh in good spirits. I have two questions regarding a disgusting narration which mentions that the Prophet, sallallahu 'alayhi wa sallam, kissed the private parts of Imam Hassan or Imam Hussein, may Allah be pleased with them.
1. Do any scholars accept the narration?
2. Does the narration carry any weight as it is narrated through many chains and was even narrated by some Companions?
Thank you.

All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.

This narration which you mentioned is weak.

Al-Bayhaqi said, “Its chain of narrators is not strong.”

Ibn Al-Qattaan said in Ahkaam An-Nathar, "It is not an authentic hadeeth.”

Ibn As-Salaah said in his commentary on Al-Waseet, “This hadeeth is weak. It was reported in As-Sunan Al-Kabeer by Al-Bayhaqi from Abu Layla Al-Ansari; it was narrated by some of his children, but their narration is not accepted or considered.”

An-Nawawi said in At-Tanqeeh, “This hadeeth is weak, and its weakness is agreed upon.”

“He also classified it as weak in his Sharh and in Khulaasat At-Tanqeeh.” [Excerpted from Al-Badr Al-Muneer]

Allah knows best.
