(Not The Final Messenger*)
Muhammad was not the father of any man among you. He was a messenger of God and the final prophet. God is fully aware of all things.
ما كانَ مُحَمَّدٌ أَبا أَحَدٍ مِن رِجالِكُم وَلٰكِن رَسولَ اللَّهِ وَخاتَمَ النَّبِيّـۧنَ وَكانَ اللَّهُ بِكُلِّ شَىءٍ عَليمًا
maa kaana Muhammmadun abaaa ahadim mir rijaalikum wa laakir Rasoolal laahi wa Khaataman Nabiyyeen; wa kaanal laahu bikulli shai’in ‘Aleema
*33:40 Despite this clear definition of Muhammad, most Muslims insist that he was the last prophet and also the last messenger. This is a tragic human trait as we see in 40:34. Those who readily believe God realize that God sent His purifying and consolidating Messenger of the Covenant after the final prophet Muhammad (3:81, 33:7).
