The sura takes its title from verse 21 which mentions the sand dunes in the country of ʻAad to whom Prophet Hud (pbuh) was sent. He warned them of the destructive consequences of their flawed thinking. The sura also discusses parents, focusing on the difficulties a mother bears. The jinn who listened to the Qurʼan are also mentioned. This is the seventh and final sura known as Hawameem (Suwer 40-46) which all start with ʻHaMeemʼ.
