It is narrated from Hazrat Qabeesah bin Mukhaariq that when the verse "And warn your nearest relatives" was revealed to the Prophet (peace be upon him), he climbed to the top of a mountain and called out, "O descendants of Abd Manaf, listen to the words of a warner! My example and yours is like that of a person who, upon seeing the enemy, goes out to warn the people of the area and begins to call out 'Ya Sabahah!'"
