(90) باب التَّرْغِيبِ فِي الْمَدِينَةِ عِنْدَ فَتْحِ الأَمْصَارِ
Sufyan b. Abd Zuhair reported Allah's Messenger (ﷺ) as saying:
Syria will be conquered and some people will go out of Medina along with their families driving their camels. and Medina is better for them if they were to know it. Then Yemen will be conquered and some people will go out of Medina along with their families driving their camels, and Medina is better for them if they were to know it. Then Iraq will be conquered and some people will go out of it along with their families driving their camels, and Medina is better for them if they were to know it.
