Muslims believe in all God's messengers

[Torch light]

Quran 3: 184, which means:
(Say [Mohammed]
"We believe in God [alone, and we assign no associate with Him],

and in what [revelation] has been revealed to us,

and that revealed to Abraham, Ishmael, Isaac, Jacob, the Tribes [: sons of Prophet Jacob]

and the [books and miracles] which Moses and Jesus and [the revelations and proofs which] the prophets received from their Lord;

we make no discrimination between anyone of them, and to Him we have submitted [ourselves.]")

[Torch light]

This belief in all God's messengers without any discrimination between them: so as to believe in some and disbelieve in others... this belief is asserted in many ayat of the Quran, like the Quran 2: 285, which means:
(The messenger [Mohammed] has now believed in [the revelation] that is revealed to him from his Lord; and the believers [have also believed];

each one [of them] believes in God, His angels, His Books, and His messengers: [the believers say:] 'We make no discrimination concerning any one of His messengers.'

They say, 'We hear and we obey. Our Lord, grant to us Your forgiveness; To You will [our] final resort be [after death.]')
