Hadith from Sahaba_ The companions of Muhammad(PBUH)..
Sahaba definition :The most widespread definition of a companion is someone who saw Muhammad, believed in him and died a Muslim. Anyone who died after rejecting Islam and becoming an apostate is not considered a companion. Those that saw him but held off believing in him until after his passing are not considered Sahaba but Tabi`in. Shi'a Muslims make no distinction between these as regards their trustworthiness
However, scholars like Javed Ghamidi and Amin Ahsan Islahi state that not every individual who met or had accidentally seen Muhammad can be considered as a Companion. In their view, the Quran has outlined a high level of faith as one of the distinctive qualities of the Sahabah. Hence, they admit to this list only those individuals who had substantial contact with Muhammad, lived with him, and took part in his campaigns and efforts at proselytizing. This view has implications in Islamic law since narrations of Muhammad transmitted through the Sahabah acquire a greater status of authenticity.
Lists of prominent companions usually run to 50 or 60 names, being the people most closely associated with Muhammad. However, there were clearly many others who had some contact with Muhammad, and their names and biographies were recorded in religious reference texts such as Ibn Sa'd al-Baghdadi's (Muḥammad ibn Sa'd) early Kitāb at-Tabāqat al-Kabīr (The book of The Major Classes). The book entitled Istî’âb fî ma’rifat-il-Ashâb by Hafidh Yusuf bin Muhammad bin Qurtubi (death 1071) consists of 2,770 biographies of male and 381 biographies of female Sahaba. According to an observation in the book entitled Mawâhib-i-ladunniyya, an untold number of persons had already converted to Islam by the time Muhammad died. There were 10,000 by the time Mecca was conquered and 70,000 during the Battle of Tabouk in 630. Some Muslims assert that they were more than 200,000 in number: it is believed that 124,000 witnessed The Farewell Sermon Muhammad delivered after making his last pilgrimage (hajj) to Mecca.
