Could you reference the narration?
Jibril (‘alayhis salam) told Muhammad (sallallahu ‘alayhi wa sallam): “There was nothing on earth that I detested more than Fir’awn. When he [proclaimed] belief [just before drowning] I stuffed his mouth with sludge, fearing that mercy would come to him.”
Imam Tabarani (rahimahullah) has recorded this narration on the authority of Sayyiduna Abu Hurayrah (radiyallahu ‘anhu).
(Al Mu’jamul Awsat, Hadith: 5819)
The narration is corroborated and suitable to quote.
(Refer: Majma’uz Zawaid, vol. 7 pg. 36)

And Allah Ta’ala Knows best.
