It is reported from Hazrat ‘Ali (radhiyallahu ‘anhu) that Rasulullah (sallallahu ‘alaihi wasallam) was once asked, “Did you ever worship an idol?” Rasulullah (sallallahu ‘alaihi wasallam) replied in the negative. He was then asked, “Did you consume wine?” Rasulullah (sallallahu ‘alaihi wasallam) again replied in the negative and remarked, “I regarded such deeds to be kufr, even though I possessed no knowledge of the book of Allah and the details of Imaan at that stage.”
