The slave who fled from his master, responsibility with regard to him was absolved.  

قَالَ رَسُولُ اللَّهِ ﷺ أَيُّمَا عَبْدٍ أَبَقَ فَقَدْ بَرِئَتْ مِنْهُ الذِّمَّةُ  

When the slave runs away from his master, his prayer is not accepted.  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَبَقَ الْعَبْدُ لَمْ تُقْبَلْ لَهُ صَلاَةٌ
