I join the congregational Salah

A: If a Ma’mum (a person being led by an Imam in Prayer) joins congregational Salah while the Imam is reciting the final Tashahhud, he should pronounce Takbirat-ul-Ihram (saying: "Allahu Akbar [Allah is the Greatest]" upon starting Prayer) once while standing. However, it is better to pronounce a second Takbir before sitting for the final Tashahhud.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
