What does « Death / To die » mean in the Quran?

And Abraham instructed his sons [to do the same] and [so did] Jacob, [saying], "O my sons, indeed Allah has chosen for you this religion, so do not die except while you are Muslims."

Or were you witnesses when death approached Jacob, when he said to his sons, "What will you worship after me?" They said, "We will worship your God and the God of your fathers, Abraham and Ishmael and Isaac - one God. And we are Muslims [in submission] to Him."

And do not say about those who are killed in the way of Allah, "They are dead." Rather, they are alive, but you perceive [it] not.

Indeed, those who disbelieve and die while they are disbelievers - upon them will be the curse of Allah and of the angels and the people, all together,

Indeed, in the creation of the heavens and earth, and the alternation of the night and the day, and the [great] ships which sail through the sea with that which benefits people, and what Allah has sent down from the heavens of rain, giving life thereby to the earth after its lifelessness and dispersing therein every [kind of] moving creature, and [His] directing of the winds and the clouds controlled between the heaven and the earth are signs for a people who use reason.

He has only forbidden to you dead animals, blood, the flesh of swine, and that which has been dedicated to other than Allah. But whoever is forced [by necessity], neither desiring [it] nor transgressing [its limit], there is no sin upon him. Indeed, Allah is Forgiving and Merciful.

Prescribed for you when death approaches [any] one of you if he leaves wealth [is that he should make] a bequest for the parents and near relatives according to what is acceptable - a duty upon the righteous.

They ask you about the sacred month - about fighting therein. Say, "Fighting therein is great [sin], but averting [people] from the way of Allah and disbelief in Him and [preventing access to] al-Masjid al-Haram and the expulsion of its people therefrom are greater [evil] in the sight of Allah. And fitnah is greater than killing." And they will continue to fight you until they turn you back from your religion if they are able. And whoever of you reverts from his religion [to disbelief] and dies while he is a disbeliever - for those, their deeds have become worthless in this world and the Hereafter, and those are the companions of the Fire, they will abide therein eternally.

Have you not considered those who left their homes in many thousands, fearing death? Allah said to them, "Die"; then He restored them to life. And Allah is full of bounty to the people, but most of the people do not show gratitude.

Have you not considered the one who argued with Abraham about his Lord [merely] because Allah had given him kingship? When Abraham said, "My Lord is the one who gives life and causes death," he said, "I give life and cause death." Abraham said, "Indeed, Allah brings up the sun from the east, so bring it up from the west." So the disbeliever was overwhelmed [by astonishment], and Allah does not guide the wrongdoing people.

Or [consider such an example] as the one who passed by a township which had fallen into ruin. He said, "How will Allah bring this to life after its death?" So Allah caused him to die for a hundred years; then He revived him. He said, "How long have you remained?" The man said, "I have remained a day or part of a day." He said, "Rather, you have remained one hundred years. Look at your food and your drink; it has not changed with time. And look at your donkey; and We will make you a sign for the people. And look at the bones [of this donkey] - how We raise them and then We cover them with flesh." And when it became clear to him, he said, "I know that Allah is over all things competent."

And [mention] when Abraham said, "My Lord, show me how You give life to the dead." [Allah] said, "Have you not believed?" He said, "Yes, but [I ask] only that my heart may be satisfied." [Allah] said, "Take four birds and commit them to yourself. Then [after slaughtering them] put on each hill a portion of them; then call them - they will come [flying] to you in haste. And know that Allah is Exalted in Might and Wise."

You cause the night to enter the day, and You cause the day to enter the night; and You bring the living out of the dead, and You bring the dead out of the living. And You give provision to whom You will without account."

And [make him] a messenger to the Children of Israel, [who will say], 'Indeed I have come to you with a sign from your Lord in that I design for you from clay [that which is] like the form of a bird, then I breathe into it and it becomes a bird by permission of Allah. And I cure the blind and the leper, and I give life to the dead - by permission of Allah. And I inform you of what you eat and what you store in your houses. Indeed in that is a sign for you, if you are believers.

Indeed, those who disbelieve and die while they are disbelievers - never would the [whole] capacity of the earth in gold be accepted from one of them if he would [seek to] ransom himself with it. For those there will be a painful punishment, and they will have no helpers.

O you who have believed, fear Allah as He should be feared and do not die except as Muslims [in submission to Him].

Here you are loving them but they are not loving you, while you believe in the Scripture - all of it. And when they meet you, they say, "We believe." But when they are alone, they bite their fingertips at you in rage. Say, "Die in your rage. Indeed, Allah is Knowing of that within the breasts."

And you had certainly wished for martyrdom before you encountered it, and you have [now] seen it [before you] while you were looking on.

Muhammad is not but a messenger. [Other] messengers have passed on before him. So if he was to die or be killed, would you turn back on your heels [to unbelief]? And he who turns back on his heels will never harm Allah at all; but Allah will reward the grateful.

And it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the grateful.

O you who have believed, do not be like those who disbelieved and said about their brothers when they traveled through the land or went out to fight, "If they had been with us, they would not have died or have been killed," so Allah makes that [misconception] a regret within their hearts. And it is Allah who gives life and causes death, and Allah is Seeing of what you do.

And if you are killed in the cause of Allah or die - then forgiveness from Allah and mercy are better than whatever they accumulate [in this world].

And whether you die or are killed, unto Allah you will be gathered.

Those who said about their brothers while sitting [at home], "If they had obeyed us, they would not have been killed." Say, "Then prevent death from yourselves, if you should be truthful."

And never think of those who have been killed in the cause of Allah as dead. Rather, they are alive with their Lord, receiving provision,
