He either wrote them down, or told the messages to his fellow companions.
There is no god but Allah and Muhammad is the messenger of Allah
It was revealed from Allah (God) to Muhammad (peace and blessings of Allah be upon him).

NOT NECESSARILY. Belief in Allah is a necessary, but insufficient condition to be a Muslim. The primary statement of belief in Islam is the Shahaada and the Shahaada has two components: (1) There is no god but Allah AND (2) Muhammad is His Messenger. Failure to believe in Muhammad's prophecy means that the person in question is not actually a Muslim.
there is not God but Allah Muhammad is messenger of Allah every human will see the result of all deeds.
He took it seriously and did as Allah told him to do.
It is a muslim creed that in latin letters say 'la ilaha illa allah muhammad rasul allah'. It means: allah is the only god, and muhammad is his profet. Hope it helps.
no prophet was a messenger between the prophet Muhammad and Allah, it was angel Gabriel.
If he submits his will to god and says that there is no god but Allah and Muhammad (P.B.U.H) is his servant and messenger.
You, as Muslim, can be satisfied when satisfying Allah (God) and His prophet Muhammad (PBUH) by following God commands and following the teachings of His prophet.
laa ilaaha illallahu muhammadur rasulallah There is no god but Allah and Muhammad is his messenger
Islam is a monotheistic religion that believe in Allah as the one true god and Muhammad as his prophet.
