"Narrated Malik bin Huwairith:\n\nI came to the Prophet (ﷺ) with some men from my tribe and stayed with him for twenty nights. He was kind and merciful to us. When he realized our longing for our families, he said to us, “Go back and stay with your families and teach them the religion, and offer the prayer and one of you should pronounce the Adhan for the prayer when its time is due and the oldest one amongst you should lead the prayer.”\n\nNarrated Abu Dhar:\n\nWe were in the company of the Prophet (ﷺ) on a journey and the Mu'adh-dhin wanted to pronounce the Adhan for the (Zuhr) prayer.
