What does « Face / Direction » mean in the Quran?

And from wherever you go out [for prayer], turn your face toward al-Masjid al-Haram. And wherever you [believers] may be, turn your faces toward it in order that the people will not have any argument against you, except for those of them who commit wrong; so fear them not but fear Me. And [it is] so I may complete My favor upon you and that you may be guided.

Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allah, the Last Day, the angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveler, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives zakah; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous.

Not upon you, [O Muhammad], is [responsibility for] their guidance, but Allah guides whom He wills. And whatever good you [believers] spend is for yourselves, and you do not spend except seeking the countenance of Allah. And whatever you spend of good - it will be fully repaid to you, and you will not be wronged.

So if they argue with you, say, "I have submitted myself to Allah [in Islam], and [so have] those who follow me." And say to those who were given the Scripture and [to] the unlearned, "Have you submitted yourselves?" And if they submit [in Islam], they are rightly guided; but if they turn away - then upon you is only the [duty of] notification. And Allah is Seeing of [His] servants.

[And mention] when the angels said, "O Mary, indeed Allah gives you good tidings of a word from Him, whose name will be the Messiah, Jesus, the son of Mary - distinguished in this world and the Hereafter and among those brought near [to Allah].

And a faction of the People of the Scripture say [to each other], "Believe in that which was revealed to the believers at the beginning of the day and reject it at its end that perhaps they will abandon their religion,

On the Day [some] faces will turn white and [some] faces will turn black. As for those whose faces turn black, [to them it will be said], "Did you disbelieve after your belief? Then taste the punishment for what you used to reject."

But as for those whose faces will turn white, [they will be] within the mercy of Allah. They will abide therein eternally.

O you who have believed, do not approach prayer while you are intoxicated until you know what you are saying or in a state of janabah, except those passing through [a place of prayer], until you have washed [your whole body]. And if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and find no water, then seek clean earth and wipe over your faces and your hands [with it]. Indeed, Allah is ever Pardoning and Forgiving.

O you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished.

And who is better in religion than one who submits himself to Allah while being a doer of good and follows the religion of Abraham, inclining toward truth? And Allah took Abraham as an intimate friend.

O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles. And if you are in a state of janabah, then purify yourselves. But if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and do not find water, then seek clean earth and wipe over your faces and hands with it. Allah does not intend to make difficulty for you, but He intends to purify you and complete His favor upon you that you may be grateful.

That is more likely that they will give testimony according to its [true] objective, or [at least] they would fear that [other] oaths might be taken after their oaths. And fear Allah and listen; and Allah does not guide the defiantly disobedient people.

And do not send away those who call upon their Lord morning and afternoon, seeking His countenance. Not upon you is anything of their account and not upon them is anything of your account. So were you to send them away, you would [then] be of the wrongdoers.

Indeed, I have turned my face toward He who created the heavens and the earth, inclining toward truth, and I am not of those who associate others with Allah."

Say, [O Muhammad], "My Lord has ordered justice and that you maintain yourselves [in worship of Him] at every place [or time] of prostration, and invoke Him, sincere to Him in religion." Just as He originated you, you will return [to life] -

And if you could but see when the angels take the souls of those who disbelieved... They are striking their faces and their backs and [saying], "Taste the punishment of the Burning Fire.

For them who have done good is the best [reward] and extra. No darkness will cover their faces, nor humiliation. Those are companions of Paradise; they will abide therein eternally

But they who have earned [blame for] evil doings - the recompense of an evil deed is its equivalent, and humiliation will cover them. They will have from Allah no protector. It will be as if their faces are covered with pieces of the night - so dark [are they]. Those are the companions of the Fire; they will abide therein eternally.

And [commanded], 'Direct your face toward the religion, inclining to truth, and never be of those who associate others with Allah;

And when the bearer of good tidings arrived, he cast it over his face, and he returned [once again] seeing. He said, "Did I not tell you that I know from Allah that which you do not know?"

And those who are patient, seeking the countenance of their Lord, and establish prayer and spend from what We have provided for them secretly and publicly and prevent evil with good - those will have the good consequence of [this] home -

Their garments of liquid pitch and their faces covered by the Fire.
