The great Muhaddith and Mujaddid (divine reformer), Shah Waliullah of Delhi, writes in his book Tafhimat al-Ilahiyah:
وختم به النبيون اى لا يوجد بعده من يأمره الله سبحانه بالتشريع على الناس
Translation: Through him (Prophet Muhammad sallallahu alaihi wasallam) the Prophets were sealed, meaning, there cannot be after him one commissioned by Allah with a Shari’ah for the people.
