عَنْ جَرِيرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ إِذَا أَبَقَ الْعَبْدُ فَلَحِقَ بِالْعَدُوِّ فَمَاتَ فَهُوَ كَافِرٌ
It is narrated from Sayyiduna Jarir bin Abdullah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: When a slave runs away and joins the enemy, and then dies in that state, he will be a disbeliever.
