Hadith text
Narrated Malik bin Huwairith:We went to the Prophet (ﷺ) and we were all young men and stayed with him for about twenty nights. The Prophet (ﷺ) was very merciful. He said, "When you return home, impart religious teachings to your families and tell them to offer perfectly such and such a prayer at such and such a time and such and such a prayer at such and such a time. And at the time of the prayer one of you should pronounce the Adhan and the oldest of you should lead the prayer
Malik bin Huwairith (رضی اللہ عنہ) bataate hain: "Hum Nabi ke paas gaye, hum sab jawan the aur unke paas taqreeban bees raatein rahe. Nabi bahut reham dil the. Unhone farmaya: 'Jab ghar wapas jao, apne gharwalon ko deeni taleem do aur unhe batao ke falaan namaz falaan waqt par aur falaan namaz falaan waqt par mukammal padhein. Aur namaz ke waqt tum mein se koi Adhan de aur sabse bada imamat kare.'"
