If we think that the door of prophethood is completely closed...
If we think that the door of prophethood is completely closed, then, God forbid, it means that the bounty (of Allah) has been cut off; and it is but a curse; and it is degrading the Prophet. It means that when Allah told his Ummat (you are best Ummat) it was a lie. God forbid, if we interpret it that in future the door of prophethood is closed in every way, then this Ummat would be the worst Ummat, instead of being the best Ummat.
It would mean that, God forbid, the Holy Prophet's (Muhammad's) spiritual power was nothing, and that he was below Hadrat Musa in his grade, because after him (Musa), hundreds of prophets came in his Ummat. But God so hates his (Muhammad's) Ummat that He talked with not a single person." (Wordings of Mirza Ghulam Ahmad Qadiani, in reply to a question published in Akhbar Al-Hakam, Qadian, 17/4/1903; as copied in the booklet "Khatm-e-Nubuwwat" (p.6) by Fakhuruddin Multani Qadiani).

I name such religion the religion of Shaitan' not the religion of Rahman'!!. (Zamima of Barahin-e-Ahmadiya, Volume 5, p. 183, by Mirza Ghulam Ahmad Qadiani).
Again commenting on the belief of the Muslims that the prophet of Islam is the last prophet, he says: "In this situation not only that the Ummat of Muhammad would remain incomplete and imperfect, but also there would be another defect that the power of bounty of the prophet of Islam would be marred and his spiritual power would be imperfect (defective)". (Al-Wasiyyat, p. 9, by Mirza Ghulam Ahmad Qadiani).
Their 2nd Khalifa writes about the Muslims' belief of "Khatm-e-Nubuwwat":- "It means that his (i.e., Muhammad's) bounty is defective and his teaching weak, so that by following it man cannot attain the maximum of highest rewards...........The belief that no prophet would be sent after the Prophet of Islam (s.a.w.) means that the Prophet of Islam (s.a.w.) prevented the world from a blessing of prophethood; and that after his coming, Allah closed this reward.
Now tell me, does this belief prove that the Prophet of Islam (s.a.w.) was ???????????? (Mercy for all the worlds) or opposite to it (God forbid)? If this belief is accepted then it means that he (i.e.
