Persian dictionaries use a slightly different order, in which Щ€ comes before Щ‡ instead of after it.Д«efore the HinduвЂ“Arabic numeral system, the abjad as numbers were used for all mathematical purposes. Modern dictionaries and other reference books use the newer hijДЃКѕД« ( Щ‡Ш¬Ш§Ш¦ЩЉ) order, which partially groups letters together by similarity of shape:ДЄ now-dated alfabaКѕД« Maghreb order exists (replaced by the Mashriqi order): ЩЉ Кѕabajd hawazin бёҐuб№Д«yin kalamnin б№ЈaКїfaбёЌin qurisat thakhudh бє“ughshin.Кѕabujadin hawazin бёҐuб№iya kalman б№ЈaКїfaбёЌ qurisat thakhudh бє“aghush.Кѕabujadin hawazin бёҐuб№iya kalman saКїfaб№Ј qurishat thakhudh бёЌaбє“ughДЄnother Abjad sequence (probably older, now mainly confined to the Maghreb), is: Шґ.Кѕabjad hawwaz бёҐuб№б№Д« kalaman saКїfaб№Ј qarashat thakhadh бёЌaбє“agh.The most common Abjad sequence, read from right to left, is: Loss of samekh was compensated for by the split of shin Ч© into two independent Arabic letters, Шґ ( shД«n) and пє± ( sД«n), which moved up to take the place of samekh. The Abjad order is not a simple historical continuation of the earlier north Semitic alphabetic order, since it has a position corresponding to the Aramaic letter samekh / semkat ЧЎ, yet no letter of the Arabic alphabet historically derives from that letter.

The Abjad order of the Arabic alphabet has two slightly different variants. Abjad numerals in Arabic are similar to the earlier alphanumeric codes of Hebrew gematria and Greek isopsephy. The Arabic Abjad system continues at this point with letters not found in other alphabets: thДЃКѕ= 500, etc. These older alphabets contained only 22 letters, stopping at taw, numerically equivalent to 400. The word Кѕabjad ( ШЈШЁШ¬ШЇ) itself derives from the first four letters (A-B-J-D) of the Semitic alphabet, including the Aramaic alphabet, Hebrew alphabet, Phoenician alphabet, and other scripts for Semitic languages.

Letters then represent the first nine intervals of 10s and those of the 100s: yДЃКѕ for 10, kДЃf for 20, qДЃf for 100, ending with 1000. In the Abjad system, the first letter of the Arabic alphabet, Кѕalif, is used to represent 1 the second letter, bДЃКѕ, 2, up to 9. In modern Arabic, the word КѕabjadД«yah ( ШЈЩЋШЁЩ’Ш¬ЩЋШЇЩђЩЉЩЋЩ‘Ш©) means ' alphabet' in general. They have been used in the Arabic-speaking world since before the eighth century when positional Arabic numerals were adopted. The Abjad numerals, also called Hisab al-Jummal ( Arabic: ШЩђШіЩЋШ§ШЁ Щ±Щ„Щ’Ш¬ЩЏЩ…ЩЋЩ‘Щ„, бёҐisДЃb al-jummal), are a decimal alphabetic numeral system/ alphanumeric code, in which the 28 letters of the Arabic alphabet are assigned numerical values.
