[Machine] The Messenger of Allah ﷺ said, "You will fight the Arabian Peninsula, and Allah will open it for you. Then you will fight Persia, and Allah will open it for you. Then you will fight the Romans, and Allah will open it for you. Then you will fight the Dajjal (false messiah), and Allah will open it for you."  

قَالَ رَسُولُ اللهِ ﷺ تُقَاتِلُونَ جَزِيرَةَالْعَرَبِ فَيَفْتَحُهَا اللهُ وَتُقَاتِلُونَ فَارِسَ فَيَفْتَحُهُمُ اللهُ وَتُقَاتِلُونَ الرُّومَ فَيَفْتَحُهُمُ اللهُ وَتُقَاتِلُونَ الدَّجَّالَ فَيَفْتَحُهُ اللهُ  

We were with Messenger of Allah ﷺ in an expedition that there came a people to Allah's Apostle ﷺ from the direction of the west. They were dressed in woollen clothes and they stood near a hillock and they met him as Messenger of Allah ﷺ was sitting. I said to myself: Better go to them and stand between him and them that they may not attack him. Then I thought that perhaps there had been going on secret negotiation amongst them. I however, went to them and stood between them and him and I remember four of the words (on that occasion) which I repeat (on the fingers of my hand) that he (Messenger of Allah) said: You will attack Arabia and Allah will enable you to conquer it, then you would attack Persia and He would make you to conquer it. Then you would attack Rome and Allah will enable you to conquer it, then you would attack the Dajjal and Allah will enable you to conquer him. Nafi' said: Jabir, we thought that the Dajjal would appear after Rome (Syrian territory) would be conquered. (Using translation from Muslim 2900)   

كُنْتُ مَعَ رَسُولِ اللهِ ﷺ فِي غَزَاةٍ فَأَتَاهُ قَوْمٌ مِنْ قِبَلِ الْمَغْرِبِ عَلَيْهِمْ ثِيَابُ الصُّوفِ فَوَافَقُوهُ عِنْدَ أَكَمَةٍ وَهُمْ قِيَامٌ وَهُوَ قَاعِدٌ فَأَتَيْتُهُ فَقُمْتُ بَيْنَهُمْ وَبَيْنَهُ فَحَفِظْتُ مِنْهُ أَرْبَعَ كَلِمَاتٍ أَعُدُّهُنَّ فِي يَدِي قَالَ تَغْزُونَ جَزِيرَةَ الْعَرَبِ فَيَفْتَحُهَا اللهُ ثُمَّ تَغْزُونَ فَارِسَ فَيَفْتَحُهَا اللهُ ثُمَّ تَغْزُونَ الرُّومَ فَيَفْتَحُهَا اللهُ ثُمَّ تَغْزُونَ الدَّجَّالَ فَيَفْتَحُهُ اللهُ قَالَ نَافِعٌ يَا جَابِرُ أَلَا تَرَى أَنَّ الدَّجَّالَ لَا يَخْرُجُ حَتَّى تُفْتَحَ الرُّومُ
