Quote by Al-Ghazali: “Knowledge without action is wastefulness and action without knowledge is foolishness.”

Knowing something but doing nothing about it is a kind of waste — you have a tool you never use. Acting without understanding what you are doing is just as bad, because it leads to mistakes and harm. Both are required together.

Al-Ghazali wrote during the Islamic Golden Age, a period of extraordinary intellectual flourishing in philosophy, science, and theology across the Abbasid Caliphate. He composed many of his works after a spiritual crisis caused him to abandon his professorship in Baghdad.

Persian philosopher, theologian, and Sufi mystic born in 1058 in Tus, in present-day Iran, widely considered one of the most influential thinkers in Islamic history. His masterwork Ihya Ulum al-Din sought to reconcile Islamic law, theology, and Sufi spirituality.
