Number of times Nabi SAW went for meraj

As Salaamu Alaikum Muftisaheb,
hope you are in good health.

Please could you answer the following question and substantiate your answer with hadith or Quraanic ayat.
Some muslims are of the opinion that our beloved Nabi(SAw) went on meraj 14 times. A certain person has lectured on the same and has caused some confusion.

We await your urgent response for the sake of clarification as the subject is still fresh.

Jazak Allah
