Is it true that Rasulullah (sawa) sentenced a couple of people to death after the conquest of Mecca, like we find in some of the books of the Seerah? Specifically, Qareeba (“the slave girl of Ibn Khatal” – Ibn Ishaq of 551), Asma bint Marwan and Nadhr Ibn al Harith, who were said to be sentenced to death for blasphemous poetry / songs (the latter also a general in the Battle of Badr). What was the reason for this? If they converted to Islam would they have been pardoned?

Prophet did not sentence them to death. The fact that it’s in the seera book doesn’t suggest it’s authentic. On the contrary, the holy prophet looked at Quraysh and said to them: “go and you are all freed”
