The word(s) "trouble" appears 7 time(s) in 7 verse(s) in Quran in Muhammad Pickthal translation.

(1) O ye who believe! Ask not of things which, if they were made unto you, would trouble you; but if ye ask of them when the Qur'an is being revealed, they will be made known unto you. Allah pardoneth this, for Allah is Forgiving, Clement.

(2) Lo! those who ward off (evil), when a glamour from the devil troubleth them, they do but remember (Allah's Guidance) and behold them seers!

(3) Had they gone forth among you they had added to you naught save trouble and had hurried to and fro among you, seeking to cause sedition among you; and among you there are some who would have listened to them. Allah is Aware of evil-doers.

(4) And they bear your loads for you unto a land ye could not reach save with great trouble to yourselves. Lo! your Lord is Full of Pity, Merciful.

(5) And when Our messengers came unto Lot, he was troubled upon their account, for he could not protect them; but they said: Fear not, nor grieve! Lo! we are to deliver thee and thy household, (all) save thy wife, who is of those who stay behind.

(6) And know that the messenger of Allah is among you. If he were to obey you in much of the government, ye would surely be in trouble; but Allah hath endeared the faith to you and hath beautified it in your hearts, and hath made disbelief and lewdness and rebellion hateful unto you. Such are they who are the rightly guided.

(7) Nay, but they have denied the truth when it came unto them, therefor they are now in troubled case.
