The word(s) "humble" appears 16 time(s) in 15 verse(s) in Quran in Muhammad Pickthal translation.

(11) Already have We grasped them with punishment, but they humble not themselves unto their Lord, nor do they pray,

(12) And (remind them of) the Day when the Trumpet will be blown, and all who are in the heavens and the earth will start in fear, save him whom Allah willeth. And all come unto Him, humbled.

(13) Lo! men who surrender unto Allah, and women who surrender, and men who believe and women who believe, and men who obey and women who obey, and men who speak the truth and women who speak the truth, and men who persevere (in righteousness) and women who persevere, and men who are humble and women who are humble, and men who give alms and women who give alms, and men who fast and women who fast, and men who guard their modesty and women who guard (their modesty), and men who remember Allah much and women who remember - Allah hath prepared for them forgiveness and a vast reward.

(14) And thou wilt see them exposed to (the Fire), made humble by disgrace, and looking with veiled eyes. And those who believe will say: Lo! the (eternal) losers are they who lose themselves and their housefolk on the Day of Resurrection. Lo! are not the wrong-doers in perpetual torment?

(15) If We had caused this Qur'an to descend upon a mountain, thou (O Muhammad) verily hadst seen it humbled, rent asunder by the fear of Allah. Such similitudes coin We for mankind that haply they may reflect.
