﴿ ٱلَّذِينَ يُبَلِّغُونَ رِسَٰلَٰتِ ٱللَّهِ وَيَخْشَوْنَهُۥ وَلَا يَخْشَوْنَ أَحَدًا إِلَّا ٱللَّهَ ۗ وَكَفَىٰ بِٱللَّهِ حَسِيبًۭا ﴾

“[and such will always be His way with] those who convey God’s messages [to the world], and stand in awe of Him, and hold none but God in awe: for none can take count [of man’s doings] as God does!”

— those who alladhīna qualifies the previous alladhīna deliver the Messages of God and fear Him and fear no one except Him and therefore they do not fear what people might say about that which God has made lawful for them. And God suffices as Reckoner as keeper of the deeds of His creatures and as One to reckon with them.
