Re: Blasphemy
From “Sirat Rasul Allah” written by Ibn Ishaq on the conquest of Mecca, Abd Abbah Ibn Hilal Ibn Khatal al-Adrami was one of the ten people to be killed along with two of his slave girls. The fault of the slave girls was that they used to sing songs ridiculing the prophet. Ibn Khatal and one of the slave girl was killed as a result.
There are other examples too.
