Answered by Shaykh Faraz Rabbani
Is the initial takbir (takbir tahreem) of any salat a fard or wajib component of the salat?
Wa Alaykum Assalam wa Rahmatullah wa Barakatuhu,
In the Name of Allah, Most Merciful & Compassionate
Saying the opening takbir is an obligatory condition of the prayer.
Specifying the words Allahu Akbar’ is necessary (and thus not permitted to leave).
This relates to both obligatory and non-obligatory prayers. [Ibn Abidin, Radd al-Muhtar; Nasafi, Kanz al-Daqa’iq]
