The word(s) "sacred" appears 16 time(s) in 13 verse(s) in Quran in Mohsin Khan translation.

(1) The sacred month is for the sacred month, and for the prohibited things, there is the Law of Equality (Qisas). Then whoever transgresses the prohibition against you, you transgress likewise against him. And fear Allah, and know that Allah is with Al-Muttaqun (the pious - See V.2:2).

(2) They ask you concerning fighting in the sacred Months (i.e. 1st, 7th, 11th and 12th months of the Islamic calendar). Say "Fighting therein is a great (transgression) but a greater (transgression) with Allah is to prevent mankind from following the Way of Allah, to disbelieve in Him, to prevent access to Al-Masjid-Al-Haram (at Makkah), and to drive out its inhabitants, and Al-Fitnah is worse than killing. And they will never cease fighting you until they turn you back from your religion (Islamic Monotheism) if they can. And whosoever of you turns back from his religion and dies as a disbeliever, then his deeds will be lost in this life and in the Hereafter, and they will be the dwellers of the Fire. They will abide therein forever."

(3) O you who believe! Violate not the sanctity of the Symbols of Allah, nor of the sacred Month, nor of the animals brought for sacrifice, nor the garlanded people or animals , and others nor the people coming to the sacred House (Makkah), seeking the bounty and good pleasure of their Lord. But when you finish the Ihram (of Hajj or 'Umrah ), you may hunt, and let not the hatred of some people in (once) stopping you from Al-Masjid-Al-Haram (at Makkah) lead you to transgression (and hostility on your part). Help you one another in Al-Birr and At-Taqwa (virtue, righteousness and piety); but do not help one another in sin and transgression. And fear Allah. Verily, Allah is Severe in punishment.

(4) Allah has made the Ka'bah, the sacred House, an asylum of security and benefits (e.g.Hajj and 'Umrah) for mankind, and also the sacred Month and the animals of offerings and the garlanded (people or animals marked with the garlands on their necks made from the outer part of the stem of the Makkah trees for their security), that you may know that Allah has knowledge of all that is in the heavens and all that is in the earth, and that Allah is the All-Knower of each and everything.

(5) Then when the sacred Months (the 1st, 7th, 11th, and 12th months of the Islamic calendar) have passed, then kill the Mushrikun (See V.2:105) wherever you find them, and capture them and besiege them, and lie in wait for them in each and every ambush. But if they repent and perform As-Salat (Iqamat-as-Salat), and give Zakat, then leave their way free. Verily, Allah is Oft-Forgiving, Most Merciful.

(6) Verily, the number of months with Allah is twelve months (in a year), so was it ordained by Allah on the Day when He created the heavens and the earth; of them four are sacred (i.e. the 1st, the 7th, the 11th and the 12th months of the Islamic calendar). That is the right religion, so wrong not yourselves therein, and fight against the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah) collectively as they fight against you collectively. But know that Allah is with those who are Al-Muttaqun (the pious - See V.2:2).

(7) The postponing (of a sacred Month) is indeed an addition to disbelief: thereby the disbelievers are led astray, for they make it lawful one year and forbid it another year in order to adjust the number of months forbidden by Allah, and make such forbidden ones lawful. The evil of their deeds is made fair-seeming to them. And Allah guides not the people who disbelieve.

(8) "O our Lord! I have made some of my offspring to dwell in an uncultivable valley by Your sacred House (the Ka'bah at Makkah) in order, O our Lord, that they may perform As-Salat (Iqamat-as-Salat). So fill some hearts among men with love towards them, and (O Allah) provide them with fruits so that they may give thanks.

(9) "Verily I am your Lord! So take off your shoes; you are in the sacred valley, Tuwa.

(10) And (remember) when We showed Ibrahim (Abraham) the site of the (sacred) House (the Ka'bah at Makkah) (saying): "Associate not anything (in worship) with Me, [La ilaha illallah (none has the right to be worshipped but Allah) - Islamic Monotheism], and sanctify My House for those who circumambulate it, and those who stand up (for prayer), and those who bow (submit themselves with humility and obedience to Allah), and make prostration (in prayer);"
