I heard Messenger of Allah ﷺ saying, "Yemen will be conquered and some people will migrate (from Medina) and will urge their families, and those who will obey them to migrate (to Yemen) although Medina will be better for them; if they but knew. Sham will also be conquered and some people will migrate (from Medina) and will urge their families and those who will obey them, to migrate (to Sham) although Medina will be better for them; if they but knew. 'Iraq will be conquered and some people will migrate (from Medina) and will urge their families and those who will obey them to migrate (to 'Iraq) although Medina will be better for them; if they but knew." (Using translation from Bukhārī 1875)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «تُفْتَحُ الْيَمَنُ فَيَأْتِي قَوْمٌ يَبُسُّون فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ وَتُفْتَحُ الشَّامُ فَيَأْتِي قَوْمٌ يَبُسُّونَ فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ وَتُفْتَحُ الْعِرَاقُ فَيَأْتِي قَوْمٌ يَبُسُّونَ فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ»

Then Syria will be conquered and some people will go away driving their camels along with them and carrying their families with them and those who are under their authority, while Medina is better for theni if they were to know it. Thtn lraq will be conquered and some people will go away (to that country) driving their camels and carrying their families with them and those who are under their authority. while Medina is better for them if they were to know it. (Using translation from Muslim 1388b)  

قَالَ النَّبِيُّ ﷺ «تُفْتَحُ الْيَمَنُ فَيَجِيءُ قَوْمٌ يَبُسُّونَ فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ ثُمَّ تُفْتَحُ الْعِرَاقُ فَيَجِيءُ قَوْمٌ يَبُسُّونَ فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ ثُمَّ تُفْتَحُ الشَّامُ فَيَجِيءُ قَوْمٌ يَبُسُّونَ فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ»
