Abdullah b. Mas'ud reported in connection with the verse
" Those whom they call upon , themselves seek the means of access to their Lord , " that it related to a group of people who worshipped a party amongst the Jinn. The group from amongst the Jinn embraced Islam , but the people kept worshipping them as they did before , and it was (on this occasion) that the verse was revealed : " Those whom they call upon , themselves seek the means of access to their Lord."
