ad-Din

ad-Din, (Arabic: الدين ‎), is a laqab, a component of some Arabic names, meaning "of the faith". The names concerned are used by Muslims all over the world.

The meaning of the word "Din", simply translated "faith", is explained further on the Dīn page.

The Arabic spelling corresponds to the letters "a l d i n", but because the letter "d" is a sun letter the letter "l" is here assimilated to it, and simply lengthens the sound of the "d". The initial vowel, written here as "a", is unstressed and can be transliterated into almost any vowel in the Latin alphabet. Spacing, hyphenation, the insertion of apostrophes and capitalisation are all variable. Commonly occurring representations are:

• al-Din
• ad-Din
• ad-Dīn
• ud-Din
• -uddin (particularly in English-speaking south and east Asia)
• -uddeen (particularly in English-speaking south and east Asia)
• -eddine (particularly in French-speaking areas)
• -ettin (particularly in Turkish names)

There are disambiguation pages for many of the names concerned, such as:
