Calling a runaway slave a kafirg
Sahih Muslim
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا جَرِيرٌ، عَنْ مُغِيرَةَ، عَنِ الشَّعْبِيِّ، قَالَ كَانَ جَرِيرُ بْنُ عَبْدِ اللَّهِ يُحَدِّثُ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِذَا أَبَقَ الْعَبْدُ لَمْ تُقْبَلْ لَهُ صَلاَةٌ " .
Jarir b. Abdullah reported it from the Holy Prophet: When the slave runs away from his master, his prayer is not accepted.
