TRINITY: A CONSIDERATION (3)

From Islamic Point of View

The confusion about the Trinity amongst Muslims and other religion followers are as follows:

While Jesus succeeds to cure the patient, his tribe surprised. And they getting respected to Israeli Allah s.w.t (Matthew 15: 31). In the Old Testament (Taurat), The God of Israel only one. Which is, how could he Christian said about the Trinity?
“The most important one,” answered Jesus, “is this: ‘Hear, O Israel, Allah s.w.t is only our God” (Mark 12: 29). This is clear that the Trinity concept is doesn’t existed.
“Well said, teacher,” the man replied. “You are right in saying that God is one and there is no other but him.” (Mark 12: 32). When Jesus saw that he had answered wisely, he said to him,” You are not far from the Kingdom of the God.” And from then on no one dared ask him any more questions. (Mark 12: 34).
Mary had lay down his son, Jesus in the manger. (Luke 2: 7). Where is the logic, when Allah s.w.t. becomes three and one of it had placed on the manger?
Jesus said, “How can you believe if you accept praise from one another, yet make not effort to obtain the praise that comes from the only one God? (John 5: 44)
Paul said, “But the God only one.” (1 Corinthians 8: 6). In this statement Paul does not said the God is One in Three and Three in One, but God is One!

So why Trinity?
