’Abdullah bin As-Sa'di narrated that The Messenger of Allah (ﷺ) said:

“Emigration (to fight the enemy) will continue as long as an enemy is fought.” Related by An-Nasa’i, and Ibn Hibban graded it as Sahih.

وَعَنْ عَبْدِ اَللَّهِ بْنِ اَلسَّعْدِيِّ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{

لَا تَنْقَطِعُ اَلْهِجْرَةُ مَا قُوتِلَ اَلْعَدُوُّ

} رَوَاهُ النَّسَائِيُّ, وَصَحَّحَهُ اِبْنُ حِبَّانَ [1]‏ .‏
