2:29
Allah created the earth (first) then He perfected the seven firmaments (heavens); He has the perfect knowledge of all things. (This verse indicates that Allah started creation by creating earth, and then He made heaven into seven heavens. This is how building usually starts, with the lower floors first and then the top floors—ibn Kathir).
Contradiction: 79:27‑30 says Allah created the heavens first.

2:34
All the angels bowed to Adam except Iblis. He was haughty and a disbeliever.
Contradiction: 16:49 says every creature in the heavens and in earth prostrates to Allah.

2:35
Allah forbade Adam and his wife to approach the tree of knowledge. (Allah spoke directly to Adam—ibn Kathir.)
Contradiction: 42:51 says Allah never speaks directly to a human; He speaks either from behind a veil or through a messenger.

2:37
Adam learned the words of inspiration from Allah. Adam was the first Muslim.
Contradiction: 2:131 says Abraham was the first Muslim.
Contradiction: 6:14 says Muhammad was the first Muslim.
Contradiction: 7:143 says Moses was the first Muslim.
Contradiction: 26:51 says some Egyptians were the first Muslims. 

2:38
Allah ordered Adam and his wife to descend on earth and to preach on people whatever message they received from Allah.
Contradiction: In verse 20:123, before sending Adam on earth, Allah told him humans on earth would be enemies of one another. This means there were already people on earth when Adam descended on it. So Adam was not the first human created by Allah. 

2:47
Allah blesses the Children of Israel more than other believers; He has preferred them above all beings.
Contradiction: 3:33‑34 says Allah preferred Adam, Noah, the house of Abraham, and the house of Imran above all beings. 

2:50
Allah parted the sea (Red sea); saved the Children of Israel (i.e., Moses’ people), and drowned Pharaoh in front of the eyes of the Children of Israel.
Contradiction: 10:90 says Pharaoh submitted to Islam.
Contradiction: 10:92 says Allah saved Pharaoh. 

2:52
Despite their sins of idolatry, Allah forgave the people of Moses.
Contradiction: 2:63 says Allah raised the Mount Sinai above the Children of Israel and threatened them to submit to Him.
Contradiction: 7:152 says Allah punished them. 

The law of contradiction means that two antithetical propositions cannot both be true at the same time and in the same sense. X cannot be non-X. A thing cannot be and not be simultaneously. And nothing that is true can be self-contradictory or inconsistent with any other truth.
All logic depends on this simple principle. Rational thought and meaningful discourse demand it. To deny it is to deny all truth in one fell swoop.
Until a little more than a hundred years ago, the law of contradiction was almost universally accepted by philosophers as a self-evident truth. Francis Schaeffer attributed the decline of 20th-century society to the demise of the law of contradiction. He suggested that when philosophy abandons this principle it sinks beneath "the line of despair" and ultimately makes suicide the only viable course of action.
Scripture very clearly affirms the law of contradiction. First John 2:21, for example, is explicit: "No lie is of the truth." Many other passages, such as 2 Timothy 2:13, ("[God] cannot deny himself") either assume or reiterate the law of contradiction.
Lots of well-meaning Christians, however, seem to operate with the misconception that biblical revelation is somehow exempt from the law of contradiction. They suggest that God's truth can contravene logic if God is so pleased. They often point to the doctrine of the Trinity or pit divine sovereignty against human responsibility as evidence that revealed truth is sometimes contradictory.
But Titus 1:2 tells us that "God . . . cannot lie." Therefore even God's Word must be in harmony with the law of contradiction. One clear, unresolvable contradiction would be enough to destroy the trustworthiness of the whole. That's why the enemies of truth are so eager to try to prove that God's Word contradicts itself.
Certainly we who love truth ought to jealously guard against any suggestion that God's revelation is internally inconsistent. But more than that, we need to defend the law of contradiction itself, because this is a biblical principle, and it lies at the root of all truth.
