Both Satan and Allah are called “deceivers”; by the Transitive Property, Allah = Satan

Satan is described as the deceiver in the Bible (Rev 12:9); Allah is described as the greatest deceiver in the Qur’an (Surah 3:54); by the transitive property of equality, what do we have?

“And they (the Jews) planned and Allah (also) planned, and Allah is the best of planners.” Surah 3:54

The word translated “plan” by most English translations of the Qur’an is actually the Arabic word “makr” meaning “To practice deceit or guile or circumvention, practice evasion or elusion, to plot, to exercise art or craft or cunning, act with policy, practice stratagem.”

I only found one translation by Dr. Ghali that didn’t obfuscate the meaning completely, although it is certainly laundered for non-Muslim sensibilities:

“And they schemed, and Allah schemed, and Allah is The Most Charitable of schemers.”

Furthermore, Surah 8:30 offers reinforcement to the notion that Allah deceives:

“And [remember, O Muhammad], when those who disbelieved plotted against you to restrain you or kill you or evict you [from Makkah]. But they plan, and Allah plans. And Allah is the best of planners (‘makr’, deceivers).“

An early Islamic commentator Qurtubi observed that some scholars have considered the words ‘best of schemers’ to be one of God’s beautiful names. Thus one would pray, ‘O Best of Schemers, scheme for me!’ Qurtubi also reports that Mohammad used to pray, ‘O God, scheme for me, and do not scheme against me!’ (Qurtubi, IV, pp. 98-99; cf. Zamakhshari, I, p. 366).” (Ibid., p. 166)

The Quran unashamedly calls Muhammad’s god the best liar and deceiver of them all! It even dares to say that ALL deception belongs completely to Allah:

“And verily, those before them did deceive/scheme (makara), but all deception/scheming is Allah’s (falillahi al-makru). He knows what every person earns, and the disbelievers will know who gets the good end.”  S. 13:42

In fact, the Quran states that Allah actually raises wicked individuals to deceive and scheme:

“Even so have we placed in every city, ringleaders of its wicked ones, to scheme therein (liyamkuroo): but only against themselves shall they scheme (yamkuroona)! and they know it not.”  S. 6:123

Moreover, the Qur’an calls Allah a liar, because he has no problem using guile, “kayd“, in Surahs 7:182-183 and 68:45. For back-up on the claim that the Qur’an describes a deceptive and lying god Allah, where much of the above information was found, see here.

The Bible calls Satan the deceiver:

“And the great dragon was thrown down, the serpent of old who is called the devil and Satan, who deceives the whole world; he was thrown down to the earth, and his angels were thrown down with him.” Rev 12:9

It also calls Satan a liar:

“You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature, for he is a liar and the father of lies.” John 8:44

By the Transitive Property of Equality, i.e., A=B, B=C, therefore A=C, we can know that Allah is actually Satan in disguise, whom the Bible calls an “angel of light” (2 Cor 11:14).
