The letter Dad, The letter unique to Arabic, the language of the Quran is called "the language of Dad"

What Dad encodes

Dad is the letter that exists only in Arabic. No other language has this sound. Arabic is traditionally called لغة الضاد (lughat al-Dad. The language of Dad). This uniqueness is itself the principle: Dad encodes what is singular, irreplaceable, specific. ضياء (diya'. Light, radiance) begins with Dad.

Ibn Arabi and the Science of Letters

The uniqueness of Dad in all human languages is understood in Ilm ul Huroof as encoding the principle of divine specificity. What is precisely what it is and nothing else. A name carrying Dad carries a quality of irreplaceability: the person cannot be substituted or approximated. They are specifically themselves.

Dad as the first letter

A name beginning with Dad produces someone with an unmistakably specific quality. There is no approximate version of them. They are exactly who they are, with a precision that makes them both difficult to substitute and difficult to fit into categories.

Dad in the Quran

Dad appears in ضالين (the straying ones, from Al-Fatiha's final verse) and ضوء (light/illumination). The letter of irreplaceable specificity appears at a crucial turning point in the Quran's most recited passage.

Names opened or shaped by Dad

Each of the following names carries the Dad principle. Either as the opening letter that governs the outward self, or within the name where it shapes the interior life. Click any name to read its full reading.

Letters whose principles interact meaningfully with Dad:

Dad joins on both sides, so it takes all four shapes. In a word it connects to the letter before it and to the letter after it, and the shape you see depends on where in the word it falls.

Dad is a sun letter. When the definite article ال (al-) comes before it, the l is not pronounced. It assimilates into Dad, which doubles instead. The word is still written with the ل, but you do not hear it. This is why الشمس is read ash-shams, not al-shams, and it is the reason these fourteen letters are called solar.
