Amr bin Salama reported,

He used to relate that his father, along with a group of his people, came as a delegation to the Messenger of Allah ﷺ when his cause had become prominent and people were learning from him. After they had attended to their needs, they asked him, "Who should lead us in prayer?"He replied, "The one among you who has memorized the most of the Quran should lead you in prayer."So they returned to their people and inquired throughout the tribe, but they found no one who had memorized more than I had. So they put me forward to lead them, and I led them in prayer while I was just a young boy wearing a small cloak of mine.He said, "I have not attended any gathering of the tribe of Jarm without being their imam to this very day."

Sahih

حدثنا عبد الواحد بن واصل الحداد حدثنا مسعر أبو الحارث الجرمي قال سمعت

عمرو بن سلمة الجرمي

يحدث أن أباه ونفرا من قومه وفدوا إلى رسول الله ﷺ حين ظهر أمره وتعلم الناس فقضوا حوائجهم ثم سألوه من يصلي لنا أو يصلي بنا فقال يصلي لكم أو بكم أكثركم جمعا للقرآن أو أخذا للقرآن فقدموا على قومهم فسألوا في الحي فلم يجدوا أحدا جمع أكثر مما جمعت فقدموني بين أيديهم فصليت بهم وأنا غلام علي شملة لي قال فما شهدت مجمعا من جرم إلا كنت إمامهم إلى يومي هذا
