Each religion has contracted its particular "spiritual disease" which prevents them from recognizing the Next Messenger; and this is mainly the fault of the religious leaders themselves.
After reading Sura of Hud, where a succession of Prophets is described, and the punishments that came upon them for their apostasy, and knowing that God does not change His method, because of this verse:
“(Such has been) the practice (approved) of Allah already in the past: no change wilt thou find in the practice (approved) of Allah. (Qur’an 48:23 YusufAli)
--my question is: Why have men concluded that God has changed His method and decided to stop sending divine Messengers?
I decided that the reason they do this is because they came to believe that Muhammad is the last Prophet ever to be sent to earth by Allah,
because of the Verse about the Seal of the Prophets; but I see no reason to believe their conclusion, since “no change wilt thou find in the practice of Allah”.
