The word(s) "precaution" appears 4 time(s) in 3 verse(s) in Quran in Muhammad Pickthal translation.

(1) O ye who believe! Take your precautions, then advance the proven ones, or advance all together.

(2) And when thou (O Muhammad) art among them and arrangest (their) worship for them, let only a party of them stand with thee (to worship) and let them take their arms. Then when they have performed their prostrations let them fall to the rear and let another party come that hath not worshipped and let them worship with thee, and let them take their precaution and their arms. Those who disbelieve long for you to neglect your arms and your baggage that they may attack you once for all. It is no sin for you to lay aside your arms, if rain impedeth you or ye are sick. But take your precaution. Lo! Allah prepareth for the disbelievers shameful punishment.

(3) If good befalleth thee (O Muhammad) it afflicteth them, and if calamity befalleth thee, they say: We took precaution, and they turn away well pleased.
