Disbelief after Belief
Indeed, those who disbelieve after having believed, then increase in disbelief, their repentance will never be accepted, and they are truly lost.
3:90Lo! those who disbelieve after their (profession of) belief, and afterward grow violent in disbelief: their repentance will not be accepted. And such are those who are astray.
16:106Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom.
How will Allah guide those who disbelieved after believing, having witnessed the truth and received clear signs?
3:86How shall Allah guide a people who disbelieved after their belief and (after) they bore witness that the messenger is true and after clear proofs (of Allah's Sovereignty) had come unto them. And Allah guideth not wrongdoing folk.
Those who believe, then disbelieve, then believe again, then disbelieve once more, Allah will not forgive them nor guide them.
4:137Lo! those who believe, then disbelieve and then (again) believe, then disbelieve, and then increase in disbelief, Allah will never pardon them, nor will He guide them unto a way.
Allah forgives what is past, but whoever repeats will face His justice.
5:95O ye who believe! Kill no wild game while ye are on the pilgrimage. Whoso of you killeth it of set purpose he shall pay its forfeit in the equivalent of that which he hath killed, of domestic animals, the judge to be two men among you known for justice, (the forfeit) to be brought as an offering to the Ka'bah; or, for expiation, he shall feed poor persons, or the equivalent thereof in fasting, that he may taste the evil consequences of his deed. Allah forgiveth whatever (of this kind) may have happened in the past, but whoso relapseth, Allah will take retribution from him. Allah is Mighty, Able to Requite (the wrong).
Perhaps your Lord will have mercy on you. But if you return to corruption, We will return to punishment.
17:8It may be that your Lord will have mercy on you, but if ye repeat (the crime) We shall repeat (the punishment), and We have appointed hell a dungeon for the disbelievers.
And whoever turns away from their faith and dies in disbelief, their deeds will be worthless in this world and the Hereafter. They will be companions of the Fire.
2:217They question thee (O Muhammad) with regard to warfare in the sacred month. Say: Warfare therein is a great (transgression), but to turn (men) from the way of Allah, and to disbelieve in Him and in the Inviolable Place of Worship, and to expel His people thence, is a greater with Allah; for persecution is worse than killing. And they will not cease from fighting against you till they have made you renegades from your religion, if they can. And whoso becometh a renegade and dieth in his disbelief: such are they whose works have fallen both in the world and the Hereafter. Such are rightful owners of the Fire: they will abide therein.
3:22Those are they whose works have failed in the world and the Hereafter; and they have no helpers.
4:18The forgiveness is not for those who do ill-deeds until, when death attendeth upon one of them, he saith: Lo! I repent now; nor yet for those who die while they are disbelievers. For such We have prepared a painful doom.
18:105Those are they who disbelieve in the revelations of their Lord and in the meeting with Him. Therefor their works are vain, and on the Day of Resurrection We assign no weight to them.
47:34Lo! those who disbelieve and turn from the way of Allah and then die disbelievers, Allah surely will not pardon them.
We will turn to what they did and make it like scattered dust.
25:23And We shall turn unto the work they did and make it scattered motes.
We will give them no weight on the Day of Judgment.
18:105Those are they who disbelieve in the revelations of their Lord and in the meeting with Him. Therefor their works are vain, and on the Day of Resurrection We assign no weight to them.
except one forced while his heart remains firm
16:106Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom.
