Takhrij Hadith 1667: "Beware of sins that are…"

Beware of sins that are deemed insignificant, for the likeness of sins that are deemed insignificant is that of a people who stopped in the bottom of a valley. One came with a stick, and another came with a stick, until they baked their bread. Indeed, when sins that are deemed insignificant overtake a person, they destroy him.
