The Messenger of Allaah (sallAllaahu ‘alayhi wa sallam) said:►
“The people should be led in prayer by the one who has most knowledge of Qur’an & has been reciting it for longer. If they are equal in their knowledge & reading of Qur’an, then they should be led by the one who made hijrah first. If they are equal with regard to hijrah, then they should be led by the one who is older…”
[Muslim 1079]
