Malik bin Huwairith rejected: We came to the Messenger of Allah ( صلی اللہ علیہ وسلم ) and we were all young men of nearly equal age. We stayed with him (the Holy Prophet) for twenty nights, and as the Messenger of Allah ( صلی اللہ علیہ وسلم ) may peace be upon him) was extremely kind and tender of heart, he therefore, thought that we were eager (to see) our family (we felt home-sickness). So he asked us about the members of the family that we had left behind and when we informed him, he said: Go back to your family, stay with them, and teach them (beliefs and practices of Islam) and exhort them to good, and when the time for prayer comes, one amongst you should-announce Adzan and then the oldest among you should lead the prayer.
