Musnad Ahmad 10:16

Al-Hakam ibn Nafi’ narrated to us, Isma’il ibn ‘Ayyash narrated to us, from Damdam ibn Zur’ah, from Shurayh ibn ‘Ubayd, tracing it back to Malik ibn Yukhāmir, from Ibn al-Sa’di, that the Prophet, peace and blessings of Allah be upon him, said: "Migration does not cease as long as the enemy is being fought." Mu’awiyah, ‘Abd al-Rahman ibn ‘Awf, and ‘Abdullah ibn ‘Amr ibn al-‘As said: The Prophet, peace and blessings of Allah be upon him, said: "Indeed, migration is of two qualities: one of them is that you migrate away from evil deeds, and the other is that you migrate to Allah and His Messenger. Migration does not cease as long as repentance is accepted, and repentance will continue to be accepted until the sun rises from the west. When it rises, every heart will be sealed with what is in it, and people will be sufficed from [further] deeds."
