The word(s) "wali" appears 35 time(s) in 35 verse(s) in Quran in Mohsin Khan translation.

(11) And Musa (Moses) chose out of his people seventy (of the best) men for Our appointed time and place of meeting, and when they were seized with a violent earthquake, he said: "O my Lord, if it had been Your Will, You could have destroyed them and me before; would You destroy us for the deeds of the foolish ones among us? It is only Your Trial by which You lead astray whom You will, and keep guided whom You will. You are our wali (Protector), so forgive us and have Mercy on us: for You are the Best of those who forgive.

(12) Verily, my wali (Protector, Supporter, and Helper) is Allah Who has revealed the Book (the Qur'an), and He protects (supports and helps) the righteous.

(13) Do you think that you shall be left alone while Allah has not yet tested those among you who have striven hard and fought and have not taken walijah [(Bitanah - helpers, advisors and consultants from disbelievers, pagans.) giving openly to them their secrets] besides Allah, and His Messenger, and the believers. Allah is Well-Acquainted with what you do.

(14) They swear by Allah that they said nothing (bad), but really they said the word of disbelief, and they disbelieved after accepting Islam, and they resolved that (plot to murder Prophet Muhammad صلى الله عليه وسلم) which they were unable to carry out, and they could not find any cause to do so except that Allah and His Messenger had enriched them of His Bounty. If then they repent, it will be better for them, but if they turn away, Allah will punish them with a painful torment in this worldly life and in the Hereafter. And there is none for them on earth as a wali (supporter, protector) or a helper.

(15) Verily, Allah! Unto Him belongs the dominion of the heavens and the earth, He gives life and He causes death. And besides Allah you have neither any wali (protector or guardian) nor any helper.

(16) "My Lord! You have indeed bestowed on me of the sovereignty, and taught me something of the interpretation of dreams - the (Only) Creator of the heavens and the earth! You are my wali (Protector, Helper, Supporter, Guardian, God, Lord.) in this world and in the Hereafter. Cause me to die as a Muslim (the one submitting to Your Will), and join me with the righteous."

(17) And thus have We sent it (the Qur'an) down to be a judgement of authority in Arabic. Were you (O Muhammad صلى الله عليه و سلم) to follow their (vain) desires after the knowledge which has come to you, then you will not have any wali (protector) or Waq (defender) against Allah.

(18) By Allah, We indeed sent (Messengers) to the nations before you (O Muhammad صلى الله عليه و سلم), but Shaitan (Satan) made their deeds fair-seeming to them. So he (Satan) is their wali (helper) today (i.e. in this world), and theirs will be a painful torment.

(19) And say: "All the praises and thanks be to Allah, Who has not begotten a son (or offspring), and Who has no partner in (His) Dominion, nor He is low to have a wali (helper, protector or supporter). And magnify Him with all magnificence, [Allahu-Akbar (Allah is the Most Great)]."

(20) And you might have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the midst of the Cave. That is (one) of the Ayat (proofs, evidence, signs) of Allah. He whom Allah guides, he is the rightly guided; but he whom He sends astray, for him you will find no wali (guiding friend) to lead him (to the right Path).
