Who precede or accompany the Imam

Q: A latecomer entered the Masjid while the Imam was bowing, so he recited Takbirat-ul-Ihram (saying: "Allahu Akbar [Allah is the Greatest]" upon starting Prayer) and followed the Imam before the latter got up from the bowing position. Is this latecomer required to make up this missed Rak`ah (unit of Prayer) after the Imam offers Taslim (salutation of peace ending the Prayer)?

A: If a latecomer or a Ma'mum (a person being led by an Imam in Prayer) pronounces Takbirat-ul-Ihram while standing, then bows and catches up with the Imam while bowing, that Rak`ah will count for him based on the Hadith narrated on the authority of Abu Bakrah (may Allah be pleased with him) who said (Part No. 7; Page No. 317) he joined the Prophet while in the bowing position, so he bowed before reaching the row, and after the Salah was over the Prophet (peace be upon him) said, May Allah increase your love for the good, but do not repeat it again (bowing in that way.) Related by Al-Bukhari. Abu Dawud added in his narration, He bowed before joining the row, and then he joined the row while bowing. It is also narrated by Abu Dawud that the Prophet (peace be upon him) said, Anyone who joins (the Salah during) Ruku` (bowing) is credited for the entire Rak`ah. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
