Q 2: If a person enters the Masjid (mosque)
and finds the Imam in the state of Ruku' (bowing), should he recite Takbir (saying: "Allahu Akbar [Allah is the Greatest]") twice (i.e. Takbirat-ul-Ihram (saying: "Allahu Akbar [Allah is the Greatest]" upon starting Prayer), then Takbirat-ul-Ruku` (saying: "Allahu Akbar [Allah is the Greatest]" before bowing), or just recite Takbirat-ul-Ihram then join the Imam in Ruku'?
He has to recite Takbirat-ul-Ihram while standing, then recite Takbirat-ul-Ruku` before he bows. In this case, he may only recite Takbirat-ul-Ihram.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
