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.
At the time of the rise of Islam in the 7th century, the main empire ruling the Mediterranean world was the Byzantine Empire. This Eastern Roman Empire had its capital in Constantinople and controlled significant territories across the eastern Mediterranean, including parts of the Balkans, North Africa, and the Near East. Concurrently, the Sassanian Empire was also a major power in the region, particularly in Persia and parts of the Arabian Peninsula. The emergence of Islam would soon lead to significant territorial changes, impacting both empires.
Constantinople and the Byzantine Empire held the Muslims at bay in the southeast (Balkans) until the rise of the Ottoman Empire in the 1300s and 1400s. In Western Europe, the Frankish Victory by Charles Martel in 732 C.E. at the Battle of Tours (called by the French as the Battle of Poitiers) against the Amazigh and Arab Islamic Forces from Spain, prevented Islam from reaching western and central Europe from the southwest (Iberia).
The Ottoman Empire conquered Constantinople, a significant Christian city, on May 29, 1453. This event marked the end of the Byzantine Empire and transformed Constantinople into the Ottoman capital, later renamed Istanbul. The conquest was a pivotal moment in history, symbolizing the rise of the Ottoman Empire and the spread of Islam in the region.
The Ottoman Empire did not directly end the Roman Empire, as the Western Roman Empire had already fallen in 476 AD, long before the rise of the Ottomans. The Eastern Roman Empire, or Byzantine Empire, continued until the Ottomans captured Constantinople in 1453. This conquest marked the end of the Byzantine Empire and solidified the Ottoman Empire's dominance in the region. Thus, while the Ottomans played a significant role in the fall of the Byzantine Empire, they did not end the Roman Empire in its entirety.

The Byzantine Empire and Sassanian Persia were the two great powers in the Middle East in the 400s-634 C.E., before the Rise of Islam.
The Byzantine Empire ensured the survival of Christianity in Europe for thousands of years. It served as a stronghold of Christian culture, preserving and spreading the religion through its territory in the Eastern Mediterranean and beyond. The Byzantine Empire's influence and protection were crucial in the face of various challenges, including invasions and the rise of Islam.

The invasion of the Byzantine Empire by the Seljuk Turks in the 11th century was significant because it marked a pivotal shift in power dynamics in the eastern Mediterranean. The Seljuk victory at the Battle of Manzikert in 1071 led to the fragmentation of Byzantine authority, paving the way for the rise of Turkish states in Anatolia. This invasion not only weakened Byzantine control but also contributed to the decline of Christian influence in the region, ultimately setting the stage for the Crusades and the eventual rise of the Ottoman Empire.
3 factors contributed to the fall of the Majapahit empire are the fact that there was the rise of many new states. Secondly, the many succession disputes in the country and last but not least, the rise of Islam.

During the seventh century, the leading absolute nation was the Byzantine Empire, which was a continuation of the Eastern Roman Empire. It was a dominant political and cultural force, known for its wealth, military strength, and influence over trade routes. The empire played a crucial role in preserving and transmitting classical knowledge during the early Middle Ages. Additionally, the rise of Islam during this period significantly impacted the geopolitical landscape, challenging Byzantine authority in the region.
The rise of Islam did not contribute to the fall of the western part of the Roman empire, which occurred about a century earlier. The rise of Islam united the Arabs who went on to conquere territories of the eastern part of the Roman Empire (historians call the eastern part after the fall of the western part Byzantine Empire). They took over Syria, Lebanon, Palestine and the territories in North Africa. Eventually, this empire was brought down by the Ottoman Turks, who were Muslim. However, the Ottomans were more interested on power and expansion than religion. Christianity did not play any part in the fall of either parts of the Roman Empire. It became the state religion and a unifying element. Some pagan Romans thought that Christianity had weakened the fighting spirit of the Romans, but this was not the case.
Islam did not contribute to the fall of Rome and the western part of the Roman Empire. This part of the empire fell more than a century before the rise of Islam. This religion contributed to the fall of the eastern part of the Roman Empire (which historians all Byzantine Empire) which existed for nearly 1,000 years after the fall of the western part. It united the Arabs, who went on to take over the Roman territories in Jordan, Palestine, Lebanon, Syria and North Africa. The Ottoman Turks took over Turkey and the European territories and conquered the Capital, Constantinople, bringing down this empire. They were Muslims. However, power, rather than religion was their motivation. Christianity did not play a part in the fall of the Roman Empire, be it the western part or the eastern part. It became the state religion and part of the fabrics of state and society. Some pagan Roman thought that Christianity had weakened the fighting spirit of the Romans, but this was not the case.
By military conquest. Islam as a religion was forced upon its constituents and adopted en mass at one point during the Ottoman Empire.
