Muslims are allowed to lie in three cases and they won’t be held liable as long as their heart remains firm in faith. Muslims may conceal their religion when they are under perceived threat. Taqiyya is “concealing or disguising one’s beliefs, convictions, ideas, feelings, opinions, and/or strategies at a time of imminent danger, whether now or later in time, to save oneself from physical and/or mental injury.” A one-word translation would be “dissimulation.”
The two forms are:
Taqiyya – Saying something that isn’t true especially if under threat, persecution, or compulsion.
Kitman – Lying by omission. An example would be when Muslim apologists quote only a fragment of verse 5:32 (that if anyone kills “it shall be as if he had killed all mankind”) while neglecting to mention that the rest of the verse (and the next) mandate murder in undefined cases of “corruption” and “mischief.”
Idtirar – lying if under threat, persecution, or compulsion.
Islamists regard war against the non-believer as perpetual, regardless of whether peace treaty exists or not. This is because any peace treaty with non-Muslims is only a temporary cease fire, or hudna, in terms of the grand plan. Therefore, taqiyya is a permitted during times of peace, as preparation for the next war has already begun.
Q2:225 – God does not hold you responsible for your unintentional oaths, but He holds you responsible for your intentions. God is Forgiving and Forbearing.
Q3:28 – Believers are not to take disbelievers for friends instead of believers. Whoever does that has nothing to do with God, unless it is to protect your own selves against them. God warns you to beware of Him. To God is the destiny.
Q3:54 – And they cheated/deceived and God cheated/deceived, and God (is) the best (of) the cheaters/deceivers.
Q3:54 – And they (- the persecutors of Jesus) planned (to crucify him) and Allah planned (to save him) and Allah is the best of the planners.
Q8:30 – And when those who disbelieved deceive/scheme at you to affix/affirm you, or kill you, or bring you out, and they scheme/deceive, and God deceives/schemes and God (is) best (of) the deceivers/schemers.
Q5:89 – God will not hold you for your unintentional oaths, but He will hold you for what oaths you have made binding; its cancellation shall be the feeding of ten poor from the average of what you feed your family, or that you clothe them, or that you free a slave; whoever cannot find shall fast for three days; this is a cancellation for making your oaths when you swear. And be careful from making oaths. It is such that God clarifies for you His revelations that you may be thankful.
Q16:106 – As for one who denies God after he has believed, with the exception of one who is forced to do it, while his heart rests securely in faith, but one who opens his heart to a denial of truth shall incur the wrath of God; such as these will have a terrible punishment.
Q40:28 – A believing person from the people of the Pharaoh who concealed his faith said, “Would you kill a man just because he says God is my Lord? He has brought you illustrious miracles from your Lord. If he speaks lies, it will only harm him, but if he speaks the Truth, some of his warnings may affect you. God does not guide a transgressing liar.
Q66:2 – Allah has certainly made lawful for you the dissolution of your oaths, and Allah is your master and He is the All-knowing, the All-wise.
Q10:100 – No one can have faith without the permission of God. God will cast down filth on those who have no understanding.
Q17:46 – We put a veil over their hearts so that they cannot understand it. We deafen their ears. When you mention your Lord in this Quran as One (Supreme Being), they run away.
Q18:57 – Who could be more wrong than the person who is reminded of his Lord’s messages and turns his back on them, ignoring what his hands are storing up for him [in the Hereafter]? We have put covers over their hearts, so they cannot understand the Quran, and We put heaviness in their ears: although you call them to guidance [Prophet] they will never accept it.
Q32:13 – Yet had We so willed, We could indeed have imposed Our guidance upon every human being: but My word shall come true: I will fill Hell with jinns and men all together.
Q16:93 – And if Allah had (so) decided, indeed He would have made you one nation; but He leads into error whomever He decides to, and He guides whomever He decides to; and indeed you will definitely be questioned about whatever you were doing.
Q35:8 – So, is he (righteous), the odiousness of whose deed (s) had been adorned (i.e., made attractive) for him, so that he sees them as fair (deeds)? Then surely Allah leads into error whomever He decides, and guides whomever He decides; so do not let yourself go away in regrets for them. Surely Allah is Ever-Knowing of whatever they work out.
Q45:23 – Have you seen the one who has chosen his desires as his lord? God has knowingly caused him to go astray, sealed his ears and heart and veiled his vision. Who besides God can guide him? Will they, then, not take heed?
-Lying is allowed in three situations; in war, between couples and two people. Any non-Muslim land is a place of war.

Ibn Shihab said he did not hear that exemption was granted in anything what the people speak as lie but in three cases: in battle, for bringing reconciliation amongst persons and the narration of the words of the husband to his wife, and the narration of the words of a wife to her husband (in a twisted form in order to bring reconciliation between them).
