وَعَنْ عُبَادَةَ بْنِ اَلصَّامِتِ رضى الله عنه
قَالَ: قَالَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ -«لَا تَغُلُّوا; فَإِنَّ اَلْغُلُولَ نَارٌ وَعَارٌ عَلَى أَصْحَابِهِ فِي اَلدُّنْيَا وَالْآخِرَةِ»
“Do not be dishonest (and treacherous) about the war booty (i.e. steal from it before it is divided legally), as Ghulul will be like fire (for the ones who got involved in it) and a cause of disgrace to those who are guilty of it in this world and in the Hereafter.” Related by Ahmad, and An-Nasai, and Ibn Hibban graded it as Sahih.
