It is narrated from Sayyiduna Abu Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The one who should lead the people in prayer is the one among them who is the best reciter of the Qur'an and the most proficient in its recitation. If they are equal in recitation, then the one who migrated first should lead. If they are equal in migration, then the oldest among them should lead. No one should lead prayer in the house or domain of another except with his permission, and likewise, no one should sit in the honored place of someone in his house except with his permission."
