The word(s) "aching" appears 32 time(s) in 30 verse(s) in Quran in Mohsin Khan translation.

(11) And recite what has been revealed to you (O Muhammad صلى الله عليه وسلم) of the Book (the Qur'an) of your Lord (i.e. recite it, understand and follow its teachings and act on its orders and preach it to men). None can change His Words, and none will you find as a refuge other than Him.

(12) And thus We have sent it down as a Qur'an in Arabic, and have explained therein in detail the warnings, in order that they may fear Allah, or that it may cause them to have a lesson from it (or to have the honour for believing and acting on its teachings).

(13) "But whosoever turns away from My Reminder (i.e. neither believes in this Qur'an nor acts on its teachings.) verily, for him is a life of hardship, and We shall raise him up blind on the Day of Resurrection."

(14) Indeed, We have sent down for you (O mankind) a Book (the Qur'an) in which there is Dhikrukum,(your Reminder or an honour for you i.e. honour for the one who follows the teaching of the Qur'an and acts on its teachings). Will you not then understand?

(15) And the Messenger (Muhammad صلى الله عليه وسلم) will say: "O my Lord! Verily, my people deserted this Qur'an (neither listened to it, nor acted on its laws and teachings).

(16) So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour with it (the Qur'an).

(17) Say: "No reward do I ask of you for this (that which I have brought from my Lord and its preaching), save that whosoever wills may take a Path to his Lord.

(18) And let them not turn you (O Muhammad صلى الله عليه وسلم) away from (preaching) the Ayat (revelations and verses) of Allah after they have been sent down to you: and invite (men) to (believe in) your Lord and be not of Al-Mushrikun (those who associate partners with Allah, e.g. polytheists, pagans, idolaters, and those who disbelieve in the Oneness of Allah and deny the Prophethood of Messenger Muhammad صلى الله عليه وسلم).

(19) Verily We have put on their necks iron collars reaching to the chins, so that their heads are raised up.

(20) They are the ones who disbelieved (in the Oneness of Allah - Islamic Monotheism) and hindered you from Al-Masjid-al-Haram (at Makkah) and detained the sacrificial animals from reaching their place of sacrifice. Had there not been believing men and believing women whom you did not know, that you may kill them and on whose account a sin would have been committed by you without (your) knowledge, that Allah might bring into His Mercy whom He wills - if they (the believers and the disbelievers) had been apart, We verily would have punished those of them who disbelieved with painful torment.
