What is the name of the Messenger Muhammad, peace and blessings be upon him, in heaven and on earth according to the Qur’an?

The question is unclear, but the names of the Prophet Muhammad and Ahmad are mentioned in the Quran. Muhammad is mentioned in His (Allah's) saying: "Muhammad is the Messenger of Allah," and Ahmad in His (Allah's) saying, recounting what Jesus (peace be upon him) said: "And bringing good tidings of a messenger to come after me, whose name is Ahmad." His grandfather, Abd al-Muttalib, named him "Muhammad," hoping that Allah would praise him in the heavens and His creation on earth.
