Can you provide the reference for this Hadith:
Sayyiduna ‘Abdullah ibnul Harith (radiyallahu ‘anhu) reported: “I have not seen anyone smile more often than the Messenger of Allah (sallallahu ‘alayhi wa sallam).”
Imam Tirmidhi (rahimahullah) has recorded this narration.
(Sunan Tirmidhi, Hadith: 3641)
Also see here.
And Allah Ta’ala Knows best.
