The word(s) "auliya" appears 34 time(s) in 31 verse(s) in Quran in Mohsin Khan translation.

(1) Allah is the Wali (Protector or Guardian) of those who believe. He brings them out from darkness into light. But as for those who disbelieve, their auliya (supporters and helpers) are Taghut [false deities and false leaders], they bring them out from light into darkness. Those are the dwellers of the Fire, and they will abide therein forever. (See V.2:81,82)

(2) Let not the believers take the disbelievers as auliya (supporters, helpers) instead of the believers, and whoever does that will never be helped by Allah in any way, except if you indeed fear a danger from them. And Allah warns you against Himself (His punishment) , and to Allah is the final return.

(3) It is only Shaitan (Satan) that suggests to you the fear of his auliya' [supporters and friends (polytheists, disbelievers in the Oneness of Allah and in His Messenger, Muhammad صلى الله عليه وسلم)]; so fear them not, but fear Me, if you are (true) believers.

(4) And whoever of you have not the means wherewith to wed free, believing women, they may wed believing girls from among those (slaves) whom your right hands possess, and Allah has full knowledge about your Faith; you are one from another. Wed them with the permission of their own folk (guardians, auliya' or masters) and give them their Mahr according to what is reasonable; they (the above said captive and slave-girls) should be chaste, not committing illegal sex, nor taking boy-friends. And after they have been taken in wedlock, if they commit illegal sexual intercourse, their punishment is half that for free (unmarried) women. This is for him among you who is afraid of being harmed in his religion or in his body; but it is better for you that you practise self-restraint, and Allah is Oft-Forgiving, Most Merciful.

(5) They wish that you reject Faith, as they have rejected (Faith), and thus that you all become equal (like one another). So take not auliya' (protectors or friends) from them, till they emigrate in the Way of Allah (to Muhammad صلى الله عليه وسلم). But if they turn back (from Islam), take (hold of) them and kill them wherever you find them, and take neither auliya' (protectors or friends) nor helpers from them.

(6) Those who take disbelievers for auliya' (protectors or helpers or friends) instead of believers, do they seek honour, power and glory with them? Verily, then to Allah belongs all honour, power and glory.

(7) O you who believe! Take not for auliya' (protectors or helpers or friends) disbelievers instead of believers. Do you wish to offer Allah a manifest proof against yourselves?

(8) O you who believe! Take not the Jews and the Christians as auliya' (friends, protectors, helpers), they are but auliya' of each other. And if any amongst you takes them (as auliya'), then surely he is one of them. Verily, Allah guides not those people who are the Zalimun (polytheists and wrong-doers and unjust).

(9) O you who believe! Take not as auliya' (protectors and helpers) those who take your religion as a mockery and fun from among those who received the Scripture (Jews and Christians) before you, and nor from among the disbelievers; and fear Allah if you indeed are true believers.

(10) You see many of them taking the disbelievers as their auliya' (protectors and helpers). Evil indeed is that which their ownselves have sent forward before them; for that (reason) Allah's Wrath fell upon them, and in torment they will abide.
