Hi everyone,

Hope all is well. Please see the comment below. 

"This numeral system has long been used to compose Arabic, Persian, and Urdu chronograms in which the sum of the numerical values of the letters in a word, phrase, or verse gives the year of a significant historical event."

Best,

Ali

FYI

Here are some classical examples of chronograms using the abjad system:

Here are some classical examples of chronograms using the abjad system:

1. "يا حافظ" (Yā Ḥāfiẓ, "O Protector!")
   • Chronogram for the completion of the Charminar in Hyderabad.
   • Abjad value = 1000 AH.
2. "جهانگير از جهان رفت" (Jahāngīr az jahān raft, "Jahangir has departed from the world.")
   • Commemorates the death of the Mughal emperor Jahangir.
   • Abjad value = 1036 AH.
3. "غالب مرد" (Ghālib murd, "Ghalib died.")
   • A famous Urdu chronogram referring to the death of the poet Mirza Ghalib.
   • Abjad value = 1277 AH.
4. "تمّ البناء" (Tamma al-bināʾ, "The building is complete.")
   • A typical inscription used to commemorate the completion of a mosque or other building.
   • The phrase is chosen so that its abjad value equals the construction year.
5. "فاز بالجنة" (Fāza bi-l-jannah, "He attained Paradise.")
   • A common style of epitaph marking a person's death.
   • The abjad value gives the year of death.

In Arabic poetry, the poet often signals the chronogram with words such as أرّخ ("date it"), أرّخوا ("date [it]"), or تأريخ ("dating" or "chronogram"), after which the final word or phrase of the poem is understood to encode the date by its abjad value.

If you can find reliable sources (i.e. published books or articles) for the above, it would be nice to add this information to one of
