Malik bin Huwayrith reported,

I came to the Messenger of Allah along with a group of us, and we were young men of about the same age. We stayed with him for twenty nights. The Messenger of Allah ﷺ was merciful and tender-hearted, and he sensed that we were missing our families, so he asked us about the family members we had left behind, and we told him.Then he said, "Go back to your families and stay among them. Teach them and instruct them. When the time for prayer comes, let one of you call the adhan, and let the eldest among you lead the prayer."

Muslim 1537
