What does « Being / Existence » mean in the Quran?

He said, "O Adam, inform them of their names." And when he had informed them of their names, He said, "Did I not tell you that I know the unseen [aspects] of the heavens and the earth? And I know what you reveal and what you have concealed."

And [mention] when We said to the angels, "Prostrate before Adam"; so they prostrated, except for Iblees. He refused and was arrogant and became of the disbelievers.

And We said, "O Adam, dwell, you and your wife, in Paradise and eat therefrom in [ease and] abundance from wherever you will. But do not approach this tree, lest you be among the wrongdoers."

But Satan caused them to slip out of it and removed them from that [condition] in which they had been. And We said, "Go down, [all of you], as enemies to one another, and you will have upon the earth a place of settlement and provision for a time."

And believe in what I have sent down confirming that which is [already] with you, and be not the first to disbelieve in it. And do not exchange My signs for a small price, and fear [only] Me.

And We shaded you with clouds and sent down to you manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not - but they were [only] wronging themselves.

But those who wronged changed [those words] to a statement other than that which had been said to them, so We sent down upon those who wronged a punishment from the sky because they were defiantly disobeying.

And [recall] when you said, "O Moses, we can never endure one [kind of] food. So call upon your Lord to bring forth for us from the earth its green herbs and its cucumbers and its garlic and its lentils and its onions." [Moses] said, "Would you exchange what is better for what is less? Go into [any] settlement and indeed, you will have what you have asked." And they were covered with humiliation and poverty and returned with anger from Allah [upon them]. That was because they [repeatedly] disbelieved in the signs of Allah and killed the prophets without right. That was because they disobeyed and were [habitually] transgressing.

Then you turned away after that. And if not for the favor of Allah upon you and His mercy, you would have been among the losers.

And you had already known about those who transgressed among you concerning the sabbath, and We said to them, "Be apes, despised."

And [recall] when Moses said to his people, "Indeed, Allah commands you to slaughter a cow." They said, "Do you take us in ridicule?" He said, "I seek refuge in Allah from being among the ignorant."

And [recall] when you slew a man and disputed over it, but Allah was to bring out that which you were concealing.

Do you covet [the hope, O believers], that they would believe for you while a party of them used to hear the words of Allah and then distort the Torah after they had understood it while they were knowing?

And when there came to them a Book from Allah confirming that which was with them - although before they used to pray for victory against those who disbelieved - but [then] when there came to them that which they recognized, they disbelieved in it; so the curse of Allah will be upon the disbelievers.

And when it is said to them, "Believe in what Allah has revealed," they say, "We believe [only] in what was revealed to us." And they disbelieve in what came after it, while it is the truth confirming that which is with them. Say, "Then why did you kill the prophets of Allah before, if you are [indeed] believers?"

And [recall] when We took your covenant and raised over you the mount, [saying], "Take what We have given you with determination and listen." They said [instead], "We hear and disobey." And their hearts absorbed [the worship of] the calf because of their disbelief. Say, "How wretched is that which your faith enjoins upon you, if you should be believers."

Say, [O Muhammad], "If the home of the Hereafter with Allah is for you alone and not the [other] people, then wish for death, if you should be truthful.

Say, "Whoever is an enemy to Gabriel - it is [none but] he who has brought the Qur'an down upon your heart, [O Muhammad], by permission of Allah, confirming that which was before it and as guidance and good tidings for the believers."

Whoever is an enemy to Allah and His angels and His messengers and Gabriel and Michael - then indeed, Allah is an enemy to the disbelievers.

And when a messenger from Allah came to them confirming that which was with them, a party of those who had been given the Scripture threw the Scripture of Allah behind their backs as if they did not know [what it contained].

And they followed [instead] what the devils had recited during the reign of Solomon. It was not Solomon who disbelieved, but the devils disbelieved, teaching people magic and that which was revealed to the two angels at Babylon, Harut and Marut. But the two angels do not teach anyone unless they say, "We are a trial, so do not disbelieve [by practicing magic]." And [yet] they learn from them that by which they cause separation between a man and his wife. But they do not harm anyone through it except by permission of Allah. And the people learn what harms them and does not benefit them. But the Children of Israel certainly knew that whoever purchased the magic would not have in the Hereafter any share. And wretched is that for which they sold themselves, if they only knew.

And if they had believed and feared Allah, then the reward from Allah would have been [far] better, if they only knew.

And they say, "None will enter Paradise except one who is a Jew or a Christian." That is [merely] their wishful thinking, Say, "Produce your proof, if you should be truthful."

The Jews say "The Christians have nothing [true] to stand on," and the Christians say, "The Jews have nothing to stand on," although they [both] recite the Scripture. Thus the polytheists speak the same as their words. But Allah will judge between them on the Day of Resurrection concerning that over which they used to differ.

And who are more unjust than those who prevent the name of Allah from being mentioned in His mosques and strive toward their destruction. It is not for them to enter them except in fear. For them in this world is disgrace, and they will have in the Hereafter a great punishment.
