(Qur’an 57: 23)

Adam said to Moosa (Moses) may peace be upon them, “Do you blame me for that which Allah had decreed upon me forty years before He created me.”

“Adam overcame Moosa in his arguments — Adam overcame Moosa in his arguments – Adam overcame Moosa in his arguments.”

The prolific English poet, Milton, said:

“Verily, the mind on its own is capable of transforming paradise into hell and hell into paradise!”

Al-Mutanabbi wrote:

“The one who is talented suffers because of (his unbalanced genius) while he is rich, Meanwhile the ignorant one is poor, and yet he is smiling.”
