It is narrated from Sayyiduna Abu Mas'ud al-Ansari (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The one most entitled to lead the people in prayer is the one who is the best reciter of the Book of Allah. If they are equal in recitation, then the one most knowledgeable of the Sunnah. If they are equal in the Sunnah, then the one who emigrated first. If they are equal in emigration, then the one oldest in age. No man should lead another in prayer within the area of his authority, nor sit in his place of honour in his house except with his permission."
