I shall guarantee him paradise.

Sahl ibn Sa’ad - radiAllahu' anhu - 

reported that the Messenger of Allah 

(shallallahu 'alaihi wa sallam) said, 

“Whoever guards what is between 

his jaws and legs. I shall guarantee 

him paradise.” - Saheeh al-Bukhari 

(8/481). A similar narrat...ion can be 

found in Muwatta of Imam Malik 

(56/11) and Sunan at-Tirmidhi.

“Should I not inform you of the sheet anchor of all this?”, 
and then took hold of his tongue and said, “Exercise 
restraint on it.”. Mu’adh - radiAllahu' anhu - enquired, “O 
Messenger of Allah, will we be held responsible for what we 
say with it?” Thereupon, the Messenger of Allah said, 
“Mu’adh, will anything else besides (irresponsible) talk cause 
the people to be thrown in the Hell-Fire upon their faces?” - 
Sunan at-Tirmidhi and Riyaadh as-Saaliheen (2/1522)

Also the Messenger of Allah (shallallahu 'alaihi wa sallam) 
said, “Most of the sins of the children of Aadam are from the 
tongue.” - At-Tabaraanee (3/87/1-2). Authenticated by al-
Haafidh al-Mundhiri in al-Targheeb (4/8)
