Mu'awiyah bin Qurrah narrated from his father that the Messenger of Allah(s.a.w) said: "When the inhabitants of Ash-Sham become corrupt, then there is no good in it for you. There will never cease to be a group in my Ummah who will be helped(by Allah), they will not be harmed by those who forsake them until the Hour is established." Muhammad bin Isma'il said: "Ali bin Al-Madini said: 'They are the people of Hadith."'
