The word(s) "train" appears 36 time(s) in 36 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) He said: "He says: A heifer not trained to till the soil or water the fields; sound and without blemish." They said: "Now hast thou brought the truth." Then they offered her in sacrifice, but not with good-will.

(2) In the Law of Equality there is (saving of) Life to you, o ye men of understanding; that ye may restrain yourselves.

(3) O ye who believe! Fasting is prescribed to you as it was prescribed to those before you, that ye may (learn) self-restraint,-

(4) Permitted to you, on the night of the fasts, is the approach to your wives. They are your garments and ye are their garments. Allah knoweth what ye used to do secretly among yourselves; but He turned to you and forgave you; so now associate with them, and seek what Allah Hath ordained for you, and eat and drink, until the white thread of dawn appear to you distinct from its black thread; then complete your fast Till the night appears; but do not associate with your wives while ye are in retreat in the mosques. Those are Limits (set by) Allah: Approach not nigh thereto. Thus doth Allah make clear His Signs to men: that they may learn self-restraint.

(5) The prohibited month for the prohibited month,- and so for all things prohibited,- there is the law of equality. If then any one transgresses the prohibition against you, Transgress ye likewise against him. But fear Allah, and know that Allah is with those who restrain themselves.

(6) Will they wait until Allah comes to them in canopies of clouds, with angels (in His train) and the question is (thus) settled? but to Allah do all questions go back (for decision).

(7) Those who spend (freely), whether in prosperity, or in adversity; who restrain anger, and pardon (all) men;- for Allah loves those who do good;-

(8) If any of you have not the means wherewith to wed free believing women, they may wed believing girls from among those whom your right hands possess: And Allah hath full knowledge about your faith. Ye are one from another: Wed them with the leave of their owners, and give them their dowers, according to what is reasonable: They should be chaste, not lustful, nor taking paramours: when they are taken in wedlock, if they fall into shame, their punishment is half that for free women. This (permission) is for those among you who fear sin; but it is better for you that ye practise self-restraint. And Allah is Oft-forgiving, Most Merciful.

(9) Then fight in Allah's cause - Thou art held responsible only for thyself - and rouse the believers. It may be that Allah will restrain the fury of the Unbelievers; for Allah is the strongest in might and in punishment.

(10) Except those who join a group between whom and you there is a treaty (of peace), or those who approach you with hearts restraining them from fighting you as well as fighting their own people. If Allah had pleased, He could have given them power over you, and they would have fought you: Therefore if they withdraw from you but fight you not, and (instead) send you (Guarantees of) peace, then Allah Hath opened no way for you (to war against them).
