Offering a second congregational Salah after the first one being offered in the Masjid

A: Offering a second congregational Salah of one of the five obligatory daily Salahs has three cases:The first case is offering a second congregational Salah before finishing the first one, which is not permissible as this contradicts the Sunnah as well as the commandment that one should offer Salah with the first congregation.The second case is coming to the Masjid after missing the congregational Salah which was offered, then a person joins one who missed the first congregation to offer Salah in a second congregation. Abu Sa`id Al-Khudry (may Allah be pleased with him) said: that Allah's Messenger (peace be upon him) saw (Part No. 6; Page No. 211) a man offering Salah alone so he (peace be upon him) asked: Is there any man who will give him charity by offering Salah with him. Related by Abu Dawud. Al-Tirmidhy related a Hadith with a similar meaning and said: This Hadith is Hasan (good Hadith). The narration of Al-Tirmidhi adds that a man stood and offered Salah with him (the man).The third case is not praying the first congregational Salah with the Imam in order to lead another congregation of those who did not attend the first congregational Salah. Doing so is an innovation in Islam, which was unknown in the early times and among its righteous predecessors. This act is Bid`ah (innovation in religion) and not permitted or approved, as it involves a great deprivation concerning the one who does not offer Salah in congregation. In fact, a Muslim is required to offer Salah at its due time with the congregation in the Masjid. If he misses the congregation and there are others like him, one of them is to lead the Salah as in the second case. And Allah knows best.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
