Al-Lu'lu Wal-Marjan 1133 — The Book of Al-Jihad (Fighting for Allâh's Cause)

'Abdullâh bin Mas'ud Narrated from:

The Prophet صلى الله عليه وسلم said, "Every betrayer (treacherous and perfidious person) will have a flag on the Day of Resurrection and that flag would be fixed, so that the betrayer (perfidious person) might be recognized by it." ( Sahîh Al-Bukhâri, Hadîth No. 410, Vol. 4 ).
