hmmmm......
the hadeeth that i mentioned earlier narrated by ABI AYYUB is in saheeh al-muslim!!
there's ayyaam al-biyd!
narrarated abu dharr radiyallaahu 3anhu...
the prophet salalaahu 3alayhi wass sallam commanded us to fast from every month three days...the 13th, 14th and the 15th!
(rawaahu an-nasaa'i wa at-tirmidhi wa sahahahu ibnu hibbaan)
AND:
Narrated ibn Umar radiyallaahu 3anhumaa , the Prophet observed the sawm on the 10th of muharram and ordered muslims to observe saum on that day, but when the fasting of the month of ramadan was prescribed, the fasting of the ashuraa was abandoned .abdullah did noit use fast on that day unless it coincided with his routine fasting by chance.
there's sawm ad-dhar but the hadeth is real long!!
........ i've got more ...hang on ok!!
HMPPHHFFT!!!
