According to my little Knowledge about Islam, I learnt that the Prophet ISA(Peace upon him) as a Muslim (UMMAT of Prophet Mohammed (peace upon him ) So Mohammed is the Last and final prophet. So there should not be any confusion about this.
Ha Ha Mr. so called Ahmed, I think you need to relook at islam again. You don't know the meaning of Nabi and a Rasool.
Rasool is a NABI who comes with a Shariah or a book or Sahifa or commandments.
All Rasools are Nabis but have this distinction over other Nabis.
The words in the Quran are(wa khaataman nabiy-yiyn -33:40)
meaning the last Nabi which automatically means the last Rasool as well, as all Rasools are Just Nabis who have been Given a book or commandments.
Hence the decision will be that no more Nabis or Rasools.
