There are thousands of secrets and pearls of wisdom in Meraj, which the scholars and saints are aware of. The verse of Surah Bani Israil, in which the heavenly journey of Meraj is mentioned, starts with the Arabic letter “Seen” of the word “Subhan" and ends with Arabic letter “Ra” of “Baseer.” If these 2 letters are combined, they become the word “Sirr,” which is the Arabic word for secret. This is an indication that Meraj is a secret from one of the secrets of Allah Ta'ala, whose truth cannot be known to anybody except Allah Ta'ala and His Holy Prophet (Sallallahu alaihi wa sallam). For this reason, Allah Ta'ala has kept this as a secret and says:
So (on that station of nearness and union) He (Allah) revealed to His (Beloved) servant whatever He revealed. Surah Najm (53:10)
