The Cow - 2:204
There are some whose words about the life of this world are pleasing to you. He keeps Allah as a witness to what is in his heart, even though he is a fierce enemy.
The hypocrites take Allah as a witness to what is in their hearts:
The Hypocrites/63:1
"When the hypocrites come to you, they say, "We bear witness that you are the messenger of Allah. Allah knows that you are His messenger, and Allah testifies that the hypocrites lie."
The Hypocrites/63:2
They take their oaths as a shield and lead astray from the way of Allah. How evil is what they do.
The Hypocrites/63:3
Because they disbelieved after they believed, so their hearts were sealed; they do not understand.
The Repentance/9:74
Although they speak words of disbelief and disbelieve after they have surrendered, they swear by Allah that they did not say them. In fact, they strived hard for what they could never attain. They sought revenge after Allah and His messenger had enriched them with His grace! It would be good for them if they repent. If they turn away, Allah will punish them with a painful torment in this world and in the Hereafter, and they will have neither friends nor helpers in the earth.
The Cow/2:8
"There are such among the people who say: "We believe in Allah and the Last Day"when in fact they do not believe."
The Cow/2:9
They seek to deceive Allah and the believers. However, they deceive themselves. They do not even realize it.
The Cow/2:75
Do you hope that they will believe in you, whereas some of them, after hearing the word of Allah, would deliberately change it.
The Cow/2:76
"When they meet the believers, they say: "We believe"; but when they are alone with them, they say: "Do you tell them what Allah has revealed to you so that they may use it as evidence against you in the sight of your Lord?"
The Family Of Imran/3:119
"You are the ones who love them even though they do not love you! Moreover, you believe in all the Scriptures. When they meet you, they say: "We believe", but when they are alone, they bite their fingers out of anger against you. Say: "May you die in your anger."Surely Allah is Knower of the essence of the breasts."
The Spoils of War/8:30
The disbelievers were plotting to neutralize you or to kill you or to drive you away. If they are plotting, Allah is plotting. Allah is the most skillful of plotters.
The Repentance/9:64
"The hypocrites fear the descent of a Surah which will inform them of what is in their hearts. Say: "Mock, Allah will reveal to you what you fear."
The Repentance/9:101
Some of the Arabs, both from among you and from the people of the city, are hypocrites. They have become arrogant in hypocrisy. You do not know them, but We know them. We will punish them with a double torment and then they will be punished with a great torment.
Muhammad/47:29
Do they not know that Allah will reveal their hatred to those in whose hearts is a disease?
Muhammad/47:30
If We had willed, We could have shown them to you, and you would have recognized them by their faces. You can recognize them by the crookedness of their words. Allah knows all that you do.
