He is the Last of the Prophets

﴿وَلَـكِن رَّسُولَ اللَّهِ وَخَاتَمَ النَّبِيِّينَ وَكَانَ اللَّهُ بِكُلِّ شَىْءٍ عَلِيماً﴾

(but he is the Messenger of Allah and the last of the Prophets. And Allah is Ever All-Aware of everything.) This is like the Ayah:

﴿اللَّهُ أَعْلَمُ حَيْثُ يَجْعَلُ رِسَالَتَهُ﴾

(Allah knows best with whom to place His Message) (6:124). This Ayah clearly states that there will be no Prophet after him. If there will be no Prophet after him then there will surely be no Messenger after him either, because the status of a Messenger is higher than that of a Prophet, for every Messenger is a Prophet but the reverse is not the case. This was reported in many Mutawatir Hadiths narrated from the Messenger of Allah via a group of his Companions, may Allah be pleased with them. Imam Ahmad recorded a narration from Ubayy bin Ka`b, from his father that the Prophet said:

«مَثَلِي فِي النَّبِيِّينَ كَمَثَلِ رَجُلٍ بَنَى دَارًا فَأَحْسَنَهَا وَأَكْمَلَهَا، وَتَرَكَ فِيهَا مَوْضِعَ لَبِنَةٍ لَمْ يَضَعْهَا، فَجَعَلَ النَّاسُ يَطُوفُونَ بِالْبُنْيَانِ وَيَعْجَبُونَ مِنْهُ وَيَقُولُونَ: لَوْ تَمَّ مَوْضِعُ هَذِهِ اللَّبِنَةِ، فَأَنَا فِي النَّبِيِّينَ مَوْضِعُ تِلْكَ اللَّبِنَة»

(My parable among the Prophets is that of a man who built a house and did a good and complete job, apart from the space of one brick which he did not put in its place. The people started to walk around the building, admiring it and saying, "If only that brick were put in its place. '' Among the Prophets, I am like that brick.) It was also recorded by At-Tirmidhi, who said "Hasan Sahih.''
