The word(s) "flee" appears 20 time(s) in 20 verse(s) in Quran in Muhammad Pickthal translation.

(1) They will not harm you save a trifling hurt, and if they fight against you they will turn and flee. And afterward they will not be helped.

(2) Allah verily made good His promise unto you when ye routed them by His leave, until (the moment) when your courage failed you, and ye disagreed about the order and ye disobeyed, after He had shown you that for which ye long. Some of you desired the world, and some of you desired the Hereafter. Therefore He made you flee from them, that He might try you. Yet now He hath forgiven you. Allah is a Lord of Kindness to believers.

(3) And, when they felt Our might, behold them fleeing from it!

(4) (But it was said unto them): flee not, but return to that (existence) which emasculated you and to your dwellings, that ye may be questioned.

(5) And throw down thy staff! But when he saw it writhing as it were a demon, he turned to flee headlong; (but it was said unto him): O Moses! Fear not! the emissaries fear not in My presence,

(6) Lo! thou canst not make the dead to hear, nor canst thou make the deaf to hear the call when they have turned to flee;

(7) Throw down thy staff. And when he saw it writhing as it had been a demon, he turned to flee headlong, (and it was said unto him): O Moses! Draw nigh and fear not. Lo! thou art of those who are secure.

(8) For verily thou (Muhammad) canst not make the dead to hear, nor canst thou make the deaf to hear the call when they have turned to flee.

(9) And when a party of them said: O folk of Yathrib! There is no stand (possible) for you, therefor turn back. And certain of them (even) sought permission of the Prophet, saying: Our homes lie open (to the enemy). And they lay not open. They but wished to flee.

(10) Say: Flight will not avail you if ye flee from death or killing, and then ye dwell in comfort but a little while.
