The word(s) "lest" appears 64 time(s) in 64 verse(s) in Quran in Muhammad Pickthal translation.

(51) The likeness of those who choose other patrons than Allah is as the likeness of the spider when she taketh unto herself a house, and lo! the frailest of all houses is the spider's house, if they but knew.

(52) O ye wives of the Prophet! Ye are not like any other women. If ye keep your duty (to Allah), then be not soft of speech, lest he in whose heart is a disease aspire (to you), but utter customary speech.

(53) And those who put away false gods lest they should worship them and turn to Allah in repentance, for them there are glad tidings. Therefor give good tidings (O Muhammad) to My bondmen

(54) lest any soul should say: Alas, my grief that I was unmindful of Allah, and I was indeed among the scoffers!

(55) And they say: Our hearts are protected from that unto which thou (O Muhammad) callest us, and in our ears there is a deafness, and between us and thee there is a veil. Act, then. Lo! we also shall be acting.

(56) Ye did not hide yourselves lest your ears and your eyes and your skins should testify against you, but ye deemed that Allah knew not much of what ye did.

(57) He hath ordained for you that religion which He commended unto Noah, and that which We inspire in thee (Muhammad), and that which We commended unto Abraham and Moses and Jesus, saying: Establish the religion, and be not divided therein. Dreadful for the idolaters is that unto which thou callest them. Allah chooseth for Himself whom He will, and guideth unto Himself him who turneth (toward Him).

(58) And lo! I have sought refuge in my Lord and your Lord lest ye stone me to death.

(59) These it was who disbelieved and debarred you from the Inviolable Place of Worship, and debarred the offering from reaching its goal. And if it had not been for believing men and believing women, whom ye know not - lest ye should tread them under foot and thus incur guilt for them unknowingly; that Allah might bring into His mercy whom He will - If (the believers and the disbelievers) had been clearly separated We verily had punished those of them who disbelieved with painful punishment.

(60) O ye who believe! Lift not up your voices above the voice of the Prophet, nor shout when speaking to him as ye shout one to another, lest your works be rendered vain while ye perceive not.
