The number 786 is considered to be a Holy number in Islam, particularly in the Indian subcontinent, where people of different religions believe in its significance. The number is derived from an ancient system of Arabic numerology called "abjad," where each letter is assigned a certain number between 1 and 1000. The Arabic phrase "Bismillah al-Rahman al-Rahim," which translates to "In the name of Allah, the Most Merciful, the Most Beneficent," has a numerical value of 786 using this system. Therefore, many Muslims from the Sub-Continent use 786 to signify this phrase. However, it is important to note that the number 786 itself has no significance in the Holy Quran or Sunnah.
