Waiting or joining Salah for someone entering the Masjid when the people are reciting Tashahhud

A: In this case, you should join them then complete Salah from the point where you joined them and make up for what you missed. If you find that they have risen from (Part No. 7; Page No. 320) the Ruku` (bowing) position of the last Rak`ah, then join them and make up for the parts you missed after the Imam recites Taslim (salutation of peace ending the Prayer). This is due to what is related by Abu Dawud (may Allah be merciful to him) on the authority of Abu Hurayrah (may Allah be pleased with him) that Allah's Messenger (peace be upon him) said, When you come to prayer while we are prostrating ourselves, prostrate yourself and do not count it as one Rak`ah. Whoever catches a Rak`ah of the Prayer, in fact catches the Prayer. Also because of the general meaning of what has been narrated by Al-Bukhari and Muslim (may Allah be merciful to them) on the authority of Abu Hurayrah (may Allah be pleased with them) that the Prophet (peace be upon him) said, When the words of Iqamah are pronounced, do not come to (prayer) running, but go with tranquility, and pray what you are in time for, and complete what you have missed... May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
