Could you give the reference for this Hadith please?
Yazid ibn Salamah Al Ju’fi (radiyallahu ‘anhu) narrates: “I said, O Rasulullah! I have heard many Hadiths from you; I fear that recent Hadiths [I heard] may cause me to forget the earlier ones. So, tell me something that would be comprehensive.’ Nabi (sallallahu ‘alayhi wa sallam) said: ‘Fear Allah in all that you know [i.e. Abstain from the prohibitions and carry out the good deeds]'”
Imam Tirmidhi (rahimahullah) has recorded this Hadith.
(Sunan Tirmidhi, Hadith: 2683)
And Allah Ta’ala Knows best.
