The word(s) "protect" appears 116 time(s) in 104 verse(s) in Quran in Mohsin Khan translation.

(31) Allah will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation feed ten Masakin (poor persons), on a scale of the average of that with which you feed your own families, or clothe them or manumit a slave. But whosoever cannot afford (that), then he should fast for three days. That is the expiation for the oaths when you have sworn . And protect your oaths (i.e. do not swear much) . Thus Allah make clear to you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that you may be grateful.

(32) Say (O Muhammad صلى الله عليه وسلم): "Shall I take as a Wali (Helper, protector, Lord or God) any other than Allah, the Creator of the heavens and the earth? And it is He Who feeds but is not fed." Say: "Verily, I am commanded to be the first of those who submit themselves to Allah (as Muslims)." And be not you (O Muhammad صلى الله عليه وسلم) of the Mushrikun [polytheists, pagans, idolaters and disbelievers in the Oneness of Allah]. (Tafsir Al-Qurtubi)

(33) And warn therewith (the Qur'an) those who fear that they will be gathered before their Lord, when there will be neither a protector nor an intercessor for them besides Him, so that they may fear Allah and keep their duty to Him (by abstaining from committing sins and by doing all kinds of good deeds which He has ordained).

(34) And leave alone those who take their religion as play and amusement, and whom the life of this world has deceived. But remind (them) with it (the Qur'an) lest a person be given up to destruction for that which he has earned, when he will find for himself no protector or intercessor besides Allah, and even if he offers every ransom, it will not be accepted from him. Such are they who are given up to destruction because of that which they have earned. For them will be a drink of boiling water and a painful torment because they used to disbelieve.

(35) For them will be the home of peace (Paradise) with their Lord. And He will be their Wali (Helper and protector) because of what they used to do.

(36) [Say (O Muhammad صلى الله عليه وسلم) to these idolaters (pagan Arabs) of your folk:] Follow what has been sent down unto you from your Lord (the Qur'an and Prophet Muhammad's Sunnah), and follow not any Auliya' (protectors and helpers who order you to associate partners in worship with Allah), besides Him (Allah). Little do you remember!

(37) O Children of Adam! Let not Shaitan (Satan) deceive you, as he got your parents [Adam and Hawwa' (Eve)] out of Paradise, stripping them of their raiments, to show them their private parts. Verily, he and Qabiluhu (his soldiers from the jinn or his tribe) see you from where you cannot see them. Verily, We made the Shayatin (devils) Auliya' (protectors and helpers) for those who believe not.

(38) A group He has guided, and a group deserved to be in error; (because) surely they took the Shayatin (devils) as Auliya' (protectors and helpers) instead of Allah, and think that they are guided.

(39) 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.

(40) 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.
