God is One

1. Hear, O Israel! The LORD is our God, the LORD is one Deut 6:4

2. I (Jesus Christ) and the Father are one John 10:30

3. Indeed, Allah is but one God Surah 4:171

The one in #1 and #2 is the same one but the one in #3 is a different one or mathematically:

1 = 2

but

1 ≠ 3
2 ≠ 3

The 3 stands alone.
