The word(s) "trained" appears 6 time(s) in 6 verse(s) in Quran in Mohsin Khan translation.

(1) He [Musa (Moses)] said, "He says, 'It is a cow neither trained to till the soil nor water the fields, sound, having no other colour except bright yellow.' " They said, "Now you have brought the truth." So they slaughtered it though they were near to not doing it.

(2) They ask you (O Muhammad صلى الله عليه وسلم) what is lawful for them (as food). Say: "Lawful unto you are At-Tayyibat [all kind of Halal (lawful-good) foods which Allah has made lawful (meat of slaughtered eatable animals, milk products, fats, vegetables and fruits)]. And those beasts and birds of prey which you have trained as hounds, training and teaching them (to catch) in the manner as directed to you by Allah; so eat of what they catch for you, but pronounce the Name of Allah over it, and fear Allah. Verily, Allah is Swift in reckoning."

(3) (Remember) when Allah will say (on the Day of Resurrection). "O 'Îsa (Jesus), son of Maryam (Mary)! Remember My Favour to you and to your mother when I supported you with Ruh-ul-Qudus [Jibril (Gabriel)] so that you spoke to the people in the cradle and in maturity; and when I taught you writing, Al-Hikmah (the power of understanding), the Taurat (Torah) and the Injeel (Gospel); and when you made out of the clay a figure like that of a bird, by My Permission, and you breathed into it, and it became a bird by My Permission, and you healed those born blind, and the lepers by My Permission, and when you brought forth the dead by My Permission; and when I restrained the Children of Israel from you (when they resolved to kill you) as you came unto them with clear proofs, and the disbelievers among them said: 'This is nothing but evident magic.'"

(4) When there were displayed before him, in the afternoon, well trained horses of the highest breed [for Jihad (holy fighting in Allah's Cause)].

(5) Allah has promised you abundant spoils that you will capture, and He has hastened for you this, and He has restrained the hands of men from you: that it may be a sign for the believers, and that He may guide you to the Straight Path.

(6) But as for him who feared standing before his Lord, and restrained himself from impure evil desires and lusts.
