The word(s) "past" appears 28 time(s) in 27 verse(s) in Quran in Mohsin Khan translation.

(11) He it is Who sends down water (rain) from the sky; from it you drink and from it (grows) the vegetation on which you send your cattle to pasture.

(12) And how many a generation (past nations) have We destroyed before them, who were better in wealth, goods and outward appearance?

(13) Eat and pasture your cattle (therein); verily, in this are Ayat (proofs and signs) for men of understanding.

(14) Had We intended to take a pastime (i.e. a wife or a son), We could surely have taken it from Us, if We were going to do (that).

(15) And (remember) Dawud (David) and Sulaiman (Solomon), when they gave judgement in the case of the field in which the sheep of certain people had pastured at night; and We were witness to their judgement.

(16) And as for women past child-bearing who do not expect wed-lock, it is no sin on them if they discard their (outer) clothing in such a way as not to show their adornment. But to refrain (i.e. not to discard their outer clothing) is better for them. And Allah is All-Hearer, All-Knower.

(17) "And this is the past favour with which you reproach me: that you have enslaved the Children of Israel."

(18) And a barrier will be set between them and that which they desire [i.e. At-Taubah (turning to Allah in repentance) and the accepting of Faith], as was done in the past with the people of their kind. Verily, they have been in grave doubt.

(19) The life of this world is but play and pastime; but if you believe (in the Oneness of Allah - Islamic Monotheism), and fear Allah, and avoid evil, He will grant you your wages, and will not ask you your wealth.

(20) That Allah may forgive you your sins of the past and the future, and complete His Favour on you, and guide you on the Straight Path,
