The word(s) "sheath" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) To Him (Alone) is referred the knowledge of the Hour. No fruit comes out of its sheath, nor does a female conceive nor brings forth (young), except by His Knowledge. And on the Day when He will call unto them (polytheists) (saying): "Where are My (so-called) partners (whom you did invent)?" They will say: "We inform You that none of us bears witness to it (that they are Your partners)!"

(2) Therein are fruits and date-palms producing sheathed fruit-stalks (enclosing dates).
