All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
The view that we adopt here in Islamweb and which we believe to be correct is that masturbation is forbidden and this is the view of the majority of the scholars as well.
As for collecting and discussing the evidence of other views, then this is not the specialty of the Fatwa Center.
The center is set up to answer the masses about matters they need regarding their religion, so that they would act accordingly. Our Center is not a research entity that collects information requested by the questioners, so we apologize for not addressing your question.
Allah knows best.
