People may throw all sorts of doubts about the Judgment and the Hereafter. The Prophet's task is not to force them to accept anything. His task is to deliver the Message of the Qur-an, and admonish those who are spiritually fit and ready to receive admonition and to prepare themselves for the new and higher life destined for man.
