Permission from parents? Ha! Proglodyte indoctrination centers don't have to answer to any cis-gender garbage...or anybody!
Oh, the five pillars of that Satanic death cult the brainwashed call Islam?
1-Women are property, at all ages...all good Muslim men can marry as many and as young as they like, beat, rape, mutlilate and kill...no limits.
2-There is no thing as not being on Jihad, Jihad is constant...there are always infidels to deal with.
3-Peace is a takkiya term, basically all lying, especially to infidels is not only encouraged, it is mandatory.
4-Infidels include all non-Muslims and those Muslims deemed blasphemous.
5-No Muslim can be charged with any crime no matter what is done if done to an infidel or an unsubmissive/un-islamic woman/servant.
