Exactly. According to Quran, there will be no other prophet after Muhammad:
"This day have I perfected for you your religion and completed My favor on you and chosen for you Islam as a religion." (Quran 5:3)
That was the last message the prophet Muhammad received from God and he revealed it during his last pilgrimage.
On that occasion, he also said:
"O people! No prophet or apostle will come after me and no new faith will be born. Reason well, therefore O people! And, understand words that I convey to you. I leave behind me two things, the Qur’an and the sunnah and if you follow these you will never go astray."
