Ar-Rahman (الرحمن) is the Name of all-encompassing divine mercy — rahma as a cosmic principle rather than a mere attribute. Ibn Arabi in the Futuhat al-Makkiyya identifies Ar-Rahman with the Nafas ar-Rahman (Breath of the Merciful), the ontological exhalation through which all existents are brought from the state of hidden potential into manifest being. Every surah of the Quran except one opens with Bismillah ar-Rahman ar-Rahim, making this Name the very threshold of revelation. The hadith qudsi 'I was a hidden treasure and loved to be known, so I created the world' is, in the Sufi reading, the self-disclosure of Ar-Rahman: creation itself is an act of rahma, the overflowing of divine generosity that gives existence to what had no claim upon it.
