Is the Takbeer Tashreeq Recited Once or Thrice?

Q: Salaah-294: Is the Takbeer Tashreeq recited once or thrice?

Answer: It is Waajib (compulsory) to recite the Takbeer Tashreeq once and not Masnoon to recite it thrice. The opinion stating that it be recited thrice is not practiced upon and Fataawaa are not issued in accordance to it. And Allaah knows best what is most correct.
