Sorry, I almost always forget that the Koran keeps silent about Yahya’s (John the Baptist) prophetic ministry! While reading from the Koran, I sometimes suppose that Mohammad’s scribes regarded Yahya as a mute prophet that could not speak throughout his life. Since there is zero info in the Koran about John after his childhood, there is also nothing about his prophetic ministry and his death - which you apparently deny on no theological or historic basis.
Nevertheless, the Koran recurrently blames Jews for murdering the messengers that were sent them by Allah. For instance:
2: 61 And humiliation and wretchedness were stamped upon them and they were visited with wrath from Allah. That was because they disbelieved in Allah’s revelations and slew the prophets wrongfully. That was for their disobedience and transgression.
3: 21. Lo! those who disbelieve the revelations of Allah, and slay the prophets wrongfully, and slay those of mankind who enjoin equity: promise them a painful doom.
5: 70. We made a covenant of old with the Children of Israel and We sent unto them messengers. As often as a messenger came unto them with that which their souls desired not (they became rebellious). Some (of them) they denied and some they slew.
I would ask you to help me devise a list of slayed messengers since your Scripture endorses the same idea of several murdered prophets.
Peace,
