Observing fast on the 13th, 4th & 15th of the lunar month

Bismillahir Rahmanir Raheem As Salamu Alaykum wa Rahmatullahi Wa Barkatuh! Abu Dharr (May Allah be pleased with him) reported: The Messenger of Allah (Sallallahu Alaihi Wasallam) said, " If you want to observe Saum on three days in a month, then fast on the thirteenth, fourteenth and fifteenth of the (lunar) month.'' [At-Tirmidhi]. Qatadah bin Milhan (May Allah be pleased with him) reported: The Messenger of Allah (Sallallahu Alaihi Wasallam) directed us to observe Saum (fasting) on the thirteenth, fourteenth and fifteenth of the (lunar) month. [Abu Dawud]. Ibn `Abbas (May Allah be pleased with them) reported: It was the practice of the Messenger of Allah (Sallallahu Alaihi Wasallam) to not to omit fast on `bright days' whether he was staying at a place or on a journey. [An-Nasa'i]. Commentary: "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. In any case, it is evident from the Ahadith mentioned here that observance of Saum on these days is more meritorious but one can do so with benefit on other days also.
