We can start with His name: How the name of Allah in Arabic forms a heart, showing us the reality of resurrection occurs with every heartbeat, literally, with thikr Allah.
Allah is also named Al-Rahman Al-Raheem, introduced to us in the first surah of the Quran, Al-Fatiha 1:1, the crown of the Quran. Here we discover that Allah the Exalted, who sustains all that exists, shows us in His names how He is the essential Yang/Yin dynamic that “powers” everything, uncontained by time, space or any constraints.

His Exalted name further expressed in the Shahada, expressing that there is no god but Allah.
And in the surah that summarizes Who Allah Is, Al-Ikhlass, we find astounding details, including the genetic code of all life PLUS the Creation Statement, by which Almighty Allah the Exalted creates, is embedded in this very short but essential surah.
