There is always a hue and cry against those activities that Muslims feel are derogatory to Islam. A recent example is the South Indian film Vishwaroopam. Such behaviour in the name of Islam is nothing but de-Islamisation of Islam as it is quite alien to Islamic scriptures. The so-called derogatory activities are not a recent phenomenon. It was very common during the prophetic and post-prophetic periods regarded as the golden era of Islam. What was the response of the Quran or the Prophet of Islam towards this phenomenon?
