Mujaahid C/Raxmaan Tuur Yare Allaha Xifdiyee is one who obeys the command of prophet Muhammad pbuh regarding the treatment of khawaarij. He says that any alshabaab member that is captured will not escape the bullet bi'dinillah.
May Allah forgive him, why did he choose the bullet and not for the perfect sword? Using the sword and cutting off their heads is nearer to the truth.
