´It was narrated from Jabir bin Samurah, that Nafi' bin 'Utbah bin Abu Waqqas narrated that the Prophet (ﷺ) said:` "You will fight the Arabian Peninsula and victory will be granted by Allah. Then you will fight the Romans and victory will be granted (by Allah). Then you will fight Dajjal and victory will be granted (by Allah)." Jabir said: "Dajjal will not appear until you have fought the Romans."

Hadith Gradingالألبانی:صحيح | زبیر علی زئی:صحيح مسلم
Benefits and Issues: ➊ The Arabian Peninsula (present-day Saudi Arabia, Yemen, Hadhramaut, Qatar, Kuwait, and part of Iraq) was conquered during the era of the Prophet sallallahu alayhi wa sallam. During the era of the Rightly Guided Caliphate, wars were fought against Rome and Persia. At that time, Rome was the principal region of the Christians. The entire region of Europe is, in terms of civilization, subordinate to it; however, now the Muslim regions are striving for independence.
➌ In this hadith, there is a prophecy regarding the dominance of Islam over Europe. After this, the Dajjal will appear. When his tribulation reaches its peak, then ‘Isa alayhis salam will descend. At that time, Islam will prevail over the entire world.
➍ The purpose of giving advance notice of these events is so that, at such times, Muslims may support the truth and not be overawed by the apparent dominance of falsehood.
