Narrated Sufyan b. Abu Zuhair:I heard Allah's Messenger (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."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنْ سُفْيَانَ بْنِ أَبِي زُهَيْرٍ ـ رضى الله عنه ـ أَنَّهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " تُفْتَحُ الْيَمَنُ فَيَأْتِي قَوْمٌ يُبِسُّونَ، فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ، وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ، وَتُفْتَحُ الشَّأْمُ، فَيَأْتِي قَوْمٌ يُبِسُّونَ فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ، وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ، وَتُفْتَحُ الْعِرَاقُ، فَيَأْتِي قَوْمٌ يُبِسُّونَ فَيَتَحَمَّلُونَ بِأَهْلِيهِمْ وَمَنْ أَطَاعَهُمْ. وَالْمَدِينَةُ خَيْرٌ لَهُمْ لَوْ كَانُوا يَعْلَمُونَ ".
