The word(s) "soft" appears 5 time(s) in 5 verse(s) in Quran in Mohsin Khan translation.

(1) And if you (O Muhammad صلى الله عليه و سلم) turn away from them (kindred, poor, wayfarer whom We have ordered you to give their rights, but if you have no money at the time they ask you for it) and you are awaiting a mercy from your Lord for which you hope, then, speak unto them a soft kind word (i.e. Allah will give me and I shall give you).

(2) And green crops (fields) and date-palms with soft spadix.

(3) O wives of the Prophet! You are not like any other women. If you keep your duty (to Allah), then be not soft in speech, lest he in whose heart is a disease (of hypocrisy, or evil desire for adultery) should be moved with desire, but speak in an honourable manner.

(4) And indeed We bestowed grace on Dawud (David) from Us (saying): "O you mountains. Glorify (Allah) with him! And you birds (also)! And We made the iron soft for him."

(5) Allah has sent down the Best Statement, a Book (this Qur'an), its parts resembling each other (in goodness and truth) (and) oft-repeated. The skins of those who fear their Lord shiver from it (when they recite it or hear it). Then their skin and their heart soften to the remembrance of Allah. That is the guidance of Allah. He Guides therewith whom He wills; and whomever Allah sends astray, for him there is no guide.
