The use of [[Ligature (writing)#Non-Latin alphabets|ligature in Arabic]] is common. There is one compulsory ligature, that for {{transliteration|ar|ALA|lām}} ل + {{transliteration|ar|ALA|alif}} ا, which exists in two forms. All other ligatures, of which there are many,<ref>{{cite web| url = https://graphemica.com/search?q=arabic+ligature| title = A list of Arabic ligature forms in Unicode.}}</ref> are optional.

A more complex ligature that combines as many as seven distinct components is commonly used to represent the word {{transliteration|ar|ALA|[[Allāh]]}} {{lang|ar|الله}}. The only ligature within the primary range of [[Arabic script in Unicode]] (U+06xx) is {{transliteration|ar|ALA|lām}} + {{transliteration|ar|ALA|alif}}. This is the only one compulsory for fonts and word-processing. Other ranges are for compatibility to older standards and contain other ligatures, which are optional.

Note: [[Unicode]] also has in its Presentation Form B FExx range a code for this ligature. If your browser and font are configured correctly for Arabic, the ligature displayed above should be identical to this one, <code>U+FEFB</code>
