Nasihah (Advice): Fast of Al-Ayyam-ul-Beed:
Jareer ibn ‘Abdullaah Radhiyallahu Anhu narrated that the Prophet Sallallaahu Alayhi Wa Sallam said: “Fasting three days of each month is fasting for a lifetime, and ayyam al-beed are the thirteenth, fourteenth and fifteenth.” (Nasaa’i)
Abu Dharr Radhiyallahu Anhu said: The Messenger of Allaah Sallallaahu Alayhi Wa Sallam said to me: “If you fast any part of the month, then fast the thirteenth, fourteenth and fifteenth.” (Tirmidhi)
“Beed” is the plural of “Abyad” which means white. Three days of 13, 14 and 15 of lunar month are called “Al-Ayyam-ul-Beed” for the reason that their nights are bright because of the moonlight. The moon begins to diminish gradually after these days.
