English Translation

Narrated Sahl bin Sa'd (may Allah be pleased with him): The Messenger of Allah (peace be upon him) said: "Whoever guarantees to me (the safekeeping of) what is between his jaws (his tongue) and what is between his legs (his private parts), I guarantee Paradise for him." (That is, that he never misuse either of these two with respect to the rights of Allah and the rights of people.)
