Apart from Muhammad, who else claims to be a prophet in his time and place?
Musallamah ibn Habib, known as "Masilmah al-Kadhab", was one of the false prophets who claimed to be a prophet at the end of the Prophet's life.  In addition to him, Taliyah among Bani Assad,  Aswad Ansi in Yemen  and Sajjah among Bani Tamim  claimed to be prophets.
Masilemeh, who falsely claimed to be a partner in the Prophet Muhammad (PBUH), wrote in a letter to the Messenger of God (PBUH): "I have shared with you in the matter of prophethood. So half of the earth is from you and half from me. But the Quraysh are a violent people.  The letter of Muslimah was brought to the Messenger of God (PBUH) by two of his messengers. The Imam asked them what they thought about Muslim. They said that our opinion is the same as what is written in this letter. The Prophet (pbuh) said: "I swear by God, if it were not disgusting for the messengers to be killed, I would be beheading you now." 
Then that Imam wrote in the reply letter of Muslimah:
From Muhammed, the Messenger of God, to a Muslim, a liar, the land belongs to God, and He inherits it from whomever He wills of His servants, and the outcome is for the righteous.”
From Muhammad, the Messenger of God (PBUH) to the false Muslim, the earth belongs to God and he inherits it to whomever he wants from his servants, and in the end it is good for the pious.
Then the Holy Prophet (PBUH) said to the Muslims: "Curse him so that his God may curse him." 
Muhammad (PBUH) is the Prophet of God and not only after him there is no prophet with whom any other prophet is not a partner.
