Sheikh Ibn Baz - Can we fast the "white days" according to the lunar (Hegirian) calendar?
Sheikh Ibn Baz (may Allah be merciful to him) was questioned : Brother `A.M.M. from Tanta, Egypt, says in his question: It is known to your Eminence that determining the beginning of ordinary lunar months is not the focus of attention of everyone. Therefore, what about fasting the White Days (13th, 14th, and 15th of every Hijri month) of every month? I mean: How can a person identify these days in order to fast them? Please advise us. May Allah reward you with the best.
Answer : It is prescribed for a person to fast them according to the calendar based on what is certain. Yet, fasting them on days other than their proper days suffices a person, because the Prophet (peace be upon him) urged the Muslims to fast them every month and did not confine fasting them to such days exclusively.
It is reported in the Two Sahih (authentic) books of Hadith (i.e., Al-Bukhari and Muslim) that the Prophet (peace be upon him) said to `Abdullah ibn `Amr ibn Al-`As (may Allah be pleased with him and his father) : “Observe fast for three days during the month; for every good deed is multiplied ten times and this is like fasting forever”.
It is stated in the Two Sahih that Abu Hurayrah (may Allah be pleased with him) said: My friend (the Prophet [peace be upon him]) advised me to observe three things : “To fast three days a month, to pray two Rak`ahs (units of Prayer) of Salat-ul-Duha (supererogatory Prayer after sunrise); and to pray Witr (Prayer with an odd number of units) before sleeping”.
There are many Hadiths that were narrated in this regard. A person has the choice either to fast them consecutively or separately, because the Hadiths did not confine fasting them consecutively. May Allah grant us success.
