Who created Allah Subhan Tallah?

If Allah has created everything then who created Allah Sub Hana Tallah. What Quran explain in this regard? This post is not a criteria to make judgment of our emaan upon Allah Subhana Tallah' saying. Its just a logical explanation for those who often raise above mentioned question. As I have not deny the fact that Allah is not created, even the starting point is that لَمۡ يَلِدۡ ۙ وَلَمۡ يُوۡلَدۡۙ.
