It is narrated from Hazrat Abu Saeed (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Where there are three people, at the time of prayer one of them should become the imam, and among them, the one who knows the most Qur'an has the greatest right to lead. It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Even after the emergence of Gog and Magog, the Hajj of the House of Allah will continue.
