Ad-Din

'''Ad-Din''' ({{langx|ar|الْدِّين}} {{Transliteration|ar|ALA-LC|ad-dīn}} {{IPA|ar|ædˈdiːn|}}, "(of) the religion/faith/creed") is a suffix component of some Arabic names in the construct case, meaning 'the religion/faith/creed', e.g. Saif ad-Din ({{langx|ar|سيف الدّين}} {{Transliteration|ar|ALA-LC|Sayf ad-Dīn}}, "Sword of the Faith"). Varieties are also used in non-Arabic names throughout the Muslim world, It is used as a family name-suffix by some royal Muslim families, including the imperial Seljuks, Walashmas, and Mughals.

It is used as a traditional naming pattern among many South Asian Muslim families of various origins. Many Hyderabadi Muslim families also use it, and many of Hyderabadis belong to the Urdu-speaking Muhajir ethnic group of Pakistan, including them.

The Arabic spelling in its standard transliteration is '''{{Lang|ar-latn|al-Din}}'''. Due to the phonological rules involving the "sun letters" ({{Lang|ar|حرف الشّمسيّة}} {{Lang|ar-latn|hurfu ’sh-Shamsiyyah}}), the Arabic letter {{Lang|ar|د}} ({{Lang|ar-latn|dāl}}) is an assimilated letter of the Arabic definite article {{Lang|ar|ال}} ({{Lang|ar-latn|al}}). This leads to the variant phonetic transliteration {{Lang|ar-latn|ad-Din}}. The first noun of the compound must have the ending -''u'', which, according to the assimilation rules in Arabic (names in general are in the nominative case), assimilates the following ''a''-, thus manifesting into {{Lang|arb-latn|ud-Din}} in Classical and Modern Standard Arabic. However, all modern Arabic vernaculars lack the noun endings. Thus, the vowel of the definite article in them is pronounced in full as either ''a'' or ''e'' (the latter mostly in Maghreb and Egypt). At the same time, the Arabic short vowel ''u'' is rendered as short ''o'' in Persian, thus {{Lang|fa-latn|od-din}}. In practice, romanizations of Arabic names containing this element may vary greatly, including: * {{Lang|ar-latn|al-Din}}, {{Lang|ar-latn|ad-Din}}, {{Lang|ar-latn|-addin}}, {{Lang|ar-latn|-adin}} * {{Lang|ar-latn|el-Din}}, {{Lang|ar-latn|-eldin}}, {{Lang|ar-latn|-eddin}} * {{Lang|ar-latn|ud-Din}}, {{Lang|ar-latn|-uddin}} (particularly in English-speaking South and East Asia), {{Lang|ar-latn|-uddeen}} (particularly in English-speaking South and East Asia) * {{Lang|ar-latn|-eddine}} (particularly in French-speaking areas) * {{Lang|ar-latn|-ettin}} (particularly in Turkish names) * {{Lang|ar-latn|-od-din}} (particularly in Persian names) * {{Lang|ar-latn|Uddin}} (particularity in South Asia) Examples of names including this element are: {{div col|colwidth=10em}} * Aladdin * Aftab al-Din * Alimuddin * Amin ud-Din * Anwaruddin * Asad ud-Din * Awwal ud-Din * Azharuddin * Azim ud-Din * Badr al-Din * Baha' al-Din * Burhan al-Din * Fakhr al-Din * Fariduddin * Ghiyath al-Din * Hamid al-Din * Haqq ad-Din * Hasan al-Din * Hisham ud-Din * Husam ad-Din * Ikhtiyar al-Din * Imad al-Din * Ismat ad-Din * Izz al-Din * Jalal ad-Din * Jamal ad-Din * Kafil al-Din * Kamal al-Din * Khair ad-Din * Majd ad-Din * Mansur ad-Din * Mizan ud-Din * Mohy al-Din * Mohyeddin * Moinuddin * Muhib ud-Din * Mufiz-ud-Din * Mu'in al-Din * Mu'iz ad-Din * Muslih ud-Din * Najm al-Din * Nasir al-Din * Nazimuddin * Nizam al-Din * Nur al-Din * Qamar ud-Din * Qutb ad-Din * Rashid al-Din * Riazuddin * Rukn al-Din * Sa'd al-Din * Sadr al-Din * Safi al-Din * Saif al-Din * Ṣalāḥ ad-Dīn * Shams al-Din * Sharaf al-Din * Shihab al-Din * Shujauddin * Sirajuddin * Taj al-Din * Taqi al-Din * Zahir al-Din * Zamir al-Din * Zayn ad-Din (or Zinedine) * Ziauddin {{div col end}}
