Islam - The Summit of Religious Evolution — Page 128
128 implies a form of worship instituted by the Holy Prophet, which, according to the above tradition, can not be changed. This interpretation is further corroborated by the Holy Prophet's wife Hazrat Ayesha: 70 "Certainly do say, he [the Holy Prophet] is the seal of all prophets, but do not say there is no prophet after him". It is thus obvious that the earliest interpretation of “Khatam-al-Nabiyyin”, during and immediately after the Prophet's death, was “Seal of Prophets” and not the “Last of Prophets”. With the benefit of hind sight and the above evidence, it will be a relatively simple exercise to scan historical records and identify any claimants in that time window that fulfill the requirement set forth by the Christian and Muslim faiths. If no claimant can be identified, then we will have to await his imminent advent.
