فالوجه في هذه الاحاديث ان من صام يوم عاشورا على طريق الحزن بمصاب رسول الله صلى الله عليه وآله والجزع لما حل بعترته فقد اصاب، ومن صامه على ما يعتقد فيه مخالفونا من الفضل في صومه والتبرك به والاعتقاد لبركته وسعادته فقد أثم واخطا.
The meaning of these hadiths is that whoever fasts the day of Ashura by way of grief over the calamity of the Messenger of Allah سبحانه وتعالى, may Allah سبحانه وتعالى bless him and his family, and anguish over what befell his progeny (itrah), then he has done correctly. And whoever fasts it according to what those who oppose us (mukhalifuna) believe regarding the merit of fasting it, seeking blessing through it, and believing in its blessing and felicity, then he has sinned and erred.
