Sahih Muslim · Book 1: The Book of Faith · Calling a runaway slave a kafirg
It is narrated on the authority of Jarir that the Messenger of Allah (may peace and blessings be upon him) observed:
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا حَفْصُ بْنُ غِيَاثٍ ، عَنْ دَاوُدَ ، عَنِ الشَّعْبِيِّ ، عَنْ جَرِيرٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَيُّ مَا عَبْدٍ أَبَقَ فَقَدْ بَرِئَتْ مِنْهُ الذِّمَّةُ " .
The slave who fled from his master, responsibility with regard to him was absolved.
