The word(s) "discard" appears 4 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And from those who call themselves Christians, We took their covenant, but they have abandoned a good part of the Message that was sent to them. So We planted amongst them enmity and hatred till the Day of Resurrection (when they discarded Allah's Book, disobeyed Allah's Messengers and His Orders and transgressed beyond bounds in Allah's disobedience); and Allah will inform them of what they used to do.

(2) 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.

(3) And indeed We sent Nuh (Noah) to his people, and he stayed among them a thousand years less fifty years [inviting them to believe in the Oneness of Allah (Monotheism), and discard the false gods and other deities]; and the Deluge overtook them while they were Zalimun (wrong-doers, polytheists, disbelievers).
