If somebody kidnaps a slave-girl and claims she is dead but her master finds her (alive)

Sahih al-Bukhari · Book 90 · Hadith 6966

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم ‏"‏ لِكُلِّ غَادِرٍ لِوَاءٌ يَوْمَ الْقِيَامَةِ يُعْرَفُ بِهِ ‏"‏‏.‏

Narrated `Abdullah bin `Umar: The Prophet (ﷺ) said, "For every betrayer there will be a flag by which he will be recognized on the Day of Resurrection. "
