All manifest and hidden sciences are incomplete without Ilm al-A‘daad, and without this science, no entity can validate its assessment and recognition upon the touchstone of experimentation. For this very reason, the entire foundation of Ilm-e-Ramal, Ilm al-Jafr, and Ilm-e-Nujoom rests upon this science alone. The entire mechanism and operation of Uloom-e-Makhfiya relies explicitly upon Ilm al-A‘daad. Without this science, all other branches of knowledge remain incomplete and ineffective.
Every single number increases its influence through its permutations, addition, division, and multiplications—meaning, through this process, the specific effects of that number are amplified. No matter how vast the scale of numbers may be, they are ultimately structured by combining the numbers from one to nine. The number one represents the absolute beginning (Ibtida), and the number nine signifies Read more [...] Ilm al-A‘daad Basic Course

Allah Almighty mentions the significance of numbers and calculations in the Holy Quran:
وَ الَّذِي جَعَلَ الشَّمْسَ ضِيَاءً وَالْقَمَرَ نُورًا وَقَدَّرَهُ مَنَازِلَ لِتَعْلَمُوا عَدَدَ السِّنِينَ وَالْحِسَابَ ۚ مَا خَلَقَ اللَّهُ ذَٰلِكَ إِلَّا بِالْحَقِّ ۚ يُفَصِّلُ الْآيَاتِ لِقَوْمٍ يَعْلَمُونَ
