The word(s) "their" appears 1609 time(s) in 1102 verse(s) in Quran in Mohsin Khan translation.

(391) And if every person who had wronged (by disbelieving in Allah and by worshipping others besides Allah) possessed all that is on the earth and sought to ransom himself therewith (it will not be accepted), and they would feel in their hearts regret when they see the torment, and they will be judged with justice, and no wrong will be done unto them.

(392) And let not their speech grieve you (O Muhammad صلى الله عليه وسلم), for all power and honour belong to Allah. He is the All-Hearer, the All-Knower.

(393) (A brief) enjoyment in this world! - and then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve [in Allah, belie His Messengers, deny and challenge His Ayat (proofs, signs, verses, etc.)].

(394) Then after him We sent Messengers to their people. They brought them clear proofs, but they would not believe what they had already rejected beforehand. Thus We seal the hearts of the transgressors (those who disbelieve in the Oneness of Allah and disobey Him).

(395) And Musa (Moses) said: "Our Lord! You have indeed bestowed on Fir'aun (Pharaoh) and his chiefs splendour and wealth in the life of this world, our Lord! that they may lead men astray from Your Path. Our Lord! Destroy their wealth, and harden their hearts, so that they will not believe until they see the painful torment."

(396) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an and none but Allah (Alone) knows their meanings]. (This is) a Book, the Verses whereof are perfected (in every sphere of knowledge), and then explained in detail from One (Allah) Who is All-Wise Well-Acquainted (with all things).

(397) No doubt! They did fold up their breasts, that they may hide from Him. Surely, even when they cover themselves with their garments, He knows what they conceal and what they reveal. Verily, He is the All-Knower of the (innermost secrets) of the breasts.

(398) Except those who show patience and do righteous good deeds: those, theirs will be forgiveness and a great reward (Paradise).

(399) Whosoever desires the life of the world and its glitter, to them We shall pay in full (the wages of) their deeds therein, and they will have no diminution therein.

(400) Can they (Muslims) who rely on a clear proof (the Qur'an) from their Lord, and whom a witness [Jibril (Gabriel عليه السلام)] from Him recites (follows) it (can they be equal with the disbelievers); and before it, came the Book of Musa (Moses), a guidance and a mercy, they believe therein, but those of the sects (Jews, Christians and all the other non-Muslim nations) that reject it (the Qur'an), the Fire will be their promised meeting-place. So be not in doubt about it (i.e. those who denied Prophet Muhammad صلى الله عليه و سلم and also denied all that which he brought from Allah. Surely, they will enter Hell). Verily, it is the truth from your Lord, but most of the mankind believe not.
