When I built the smaller mosque that is attached to my residence and is built above an alley, I thought of finding a date in terms of numerical value1. At this, the following words were revealed from God Almighty:
[This mosque is a source of blessings, and is blessed itself. In it will be performed every blessed deed].
This was a prophecy from which the date of the foundation of the mosque is also derived.
1 In the Arabic abjad system each letter in the alphabet corresponds to a numerical value. Using this system, the date of the founding of the mosque, year 1300 of the Hijrah calendar, equals the sum of the numerical values of each Arabic letter used in the sentence. [Publisher]
