Before the spread of Islam in the 7th Century CE,\, there were two forces that controlled Middle East and Europe. These lands were ruled by Romans and Persians. During the time of rise of Islam these two empires were engaged in heavy warfare, and both lands especially the Persian Empire was devastated and left in ruins. It wasn't too difficult for the new Muslim army to defeat this tired and devastated empire.
Once Muslims conquered the Persian Empire, the Muslim religion spread rather quickly. The reasons for this could be many, but here are two logical ones.
1) Before the fall of the Sassanian Persian Empire, the Zoroastrian priests had much power in the state and they had become very corrupt. The people of the land were tired of these corrupt priests and were ready to embrace a new religion.
2) The tax imposed on non-muslims by the Muslim rulers were heavy, therefore it was to the benefit of the people to embrace the new religion in order to not pay the taxes. Many of the local elites also saw this as a way to gain power in the new empire.

The Byzantine Empire declined after Islam spread. The words "Islam spread" are nebulous. If the question is referring to the Rise of Islam period, when Mohammed and the Rightly-Guided Caliphs were spreading Islam, then yes, the Byzantine Empire decline after these events. If, however, you are referring to the Seljuk and Ottoman conquests of Anatolia nearly 600 years later which eventually ended the Byzantine Empire, the Empire was in decline long before these armies trampled the Byzantines to the ground. The answer is more complex than the above answers would purport. See the link below for another relevant answer.
