The word(s) "crooked" appears 10 time(s) in 10 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Say: "O ye People of the Book! Why obstruct ye those who believe, from the path of Allah, Seeking to make it crooked, while ye were yourselves witnesses (to Allah's Covenant)? but Allah is not unmindful of all that ye do."

(2) "Those who would hinder (men) from the path of Allah and would seek in it something crooked: they were those who denied the Hereafter."

(3) "And squat not on every road, breathing threats, hindering from the path of Allah those who believe in Him, and seeking in it something crooked; But remember how ye were little, and He gave you increase. And hold in your mind's eye what was the end of those who did mischief.

(4) "Those who would hinder (men) from the path of Allah and would seek in it something crooked: these were they who denied the Hereafter!"

(5) Those who love the life of this world more than the Hereafter, who hinder (men) from the Path of Allah and seek therein something crooked: they are astray by a long distance.

(6) Praise be to Allah, Who hath sent to His Servant the Book, and hath allowed therein no crookedness:

(7) "Nothing crooked or curved wilt thou see in their place."

(8) On that Day will they follow the Caller (straight): no crookedness (can they show) him: all sounds shall humble themselves in the Presence of (Allah) Most Gracious: nothing shalt thou hear but the tramp of their feet (as they march).

(9) (It is) a Qur'an in Arabic, without any crookedness (therein): in order that they may guard against Evil.

(10) Turnest thou not thy sight towards those who were forbidden secret counsels yet revert to that which they were forbidden (to do)? And they hold secret counsels among themselves for iniquity and hostility, and disobedience to the Messenger. And when they come to thee, they salute thee, not as Allah salutes thee, (but in crooked ways): And they say to themselves, "Why does not Allah punish us for our words?" Enough for them is Hell: In it will they burn, and evil is that destination!
